So if there is an impl of `T:Foo<'a>` that applies to - // all `'a`, then we must know that `T:Bar<'a,'a>` holds for all - // `'a`. - // - // Another example to be careful of is this: - // - // trait Foo1<'a>: for<'b> Bar1<'a,'b> { } - // trait Bar1<'b,'c> { } - // - // Here, if we have `for<'x> T: Foo1<'x>`, then what do we know? - // The answer is that we know `for<'x,'b> T: Bar1<'x,'b>`. The - // reason is similar to the previous example: any impl of - // `T:Foo1<'x>` must show that `for<'b> T: Bar1<'x, 'b>`. So - // basically we would want to collapse the bound lifetimes from - // the input (`trait_ref`) and the supertraits. - // - // To achieve this in practice is fairly straightforward. Let's - // consider the more complicated scenario: - // - // - We start out with `for<'x> T: Foo1<'x>`. In this case, `'x` - // has a De Bruijn index of 1. We want to produce `for<'x,'b> T: Bar1<'x,'b>`, - // where both `'x` and `'b` would have a DB index of 1. - // The substitution from the input trait-ref is therefore going to be - // `'a => 'x` (where `'x` has a DB index of 1). - // - The supertrait-ref is `for<'b> Bar1<'a,'b>`, where `'a` is an - // early-bound parameter and `'b` is a late-bound parameter with a - // DB index of 1. - // - If we replace `'a` with `'x` from the input, it too will have - // a DB index of 1, and thus we'll have `for<'x,'b> Bar1<'x,'b>` - // just as we wanted. - // - // There is only one catch. If we just apply the substitution `'a - // => 'x` to `for<'b> Bar1<'a,'b>`, the substitution code will - // adjust the DB index because we substituting into a binder (it - // tries to be so smart...) resulting in `for<'x> for<'b> - // Bar1<'x,'b>` (we have no syntax for this, so use your - // imagination). Basically the 'x will have DB index of 2 and 'b - // will have DB index of 1. Not quite what we want.

So if there is an impl of `T:Foo<'a>` that applies to + // all `'a`, then we must know that `T:Bar<'a,'a>` holds for all + // `'a`. + // + // Another example to be careful of is this: + // + // trait Foo1<'a>: for<'b> Bar1<'a,'b> { } + // trait Bar1<'b,'c> { } + // + // Here, if we have `for<'x> T: Foo1<'x>`, then what do we know? + // The answer is that we know `for<'x,'b> T: Bar1<'x,'b>`. The + // reason is similar to the previous example: any impl of + // `T:Foo1<'x>` must show that `for<'b> T: Bar1<'x, 'b>`. So + // basically we would want to collapse the bound lifetimes from + // the input (`trait_ref`) and the supertraits. + // + // To achieve this in practice is fairly straightforward. Let's + // consider the more complicated scenario: + // + // - We start out with `for<'x> T: Foo1<'x>`. In this case, `'x` + // has a De Bruijn index of 1. We want to produce `for<'x,'b> T: Bar1<'x,'b>`, + // where both `'x` and `'b` would have a DB index of 1. + // The substitution from the input trait-ref is therefore going to be + // `'a => 'x` (where `'x` has a DB index of 1). + // - The supertrait-ref is `for<'b> Bar1<'a,'b>`, where `'a` is an + // early-bound parameter and `'b` is a late-bound parameter with a + // DB index of 1. + // - If we replace `'a` with `'x` from the input, it too will have + // a DB index of 1, and thus we'll have `for<'x,'b> Bar1<'x,'b>` + // just as we wanted. + // + // There is only one catch.

The `Coroutine::Return` type is the returned type of the +coroutine. This is typically the last expression in a coroutine's definition or +any value passed to `return` in a coroutine. The `resume` function is the entry +point for executing the `Coroutine` itself. + +The return value of `resume`, `CoroutineState`, looks like: + +```rust +pub enum CoroutineState { + Yielded(Y), + Complete(R), +} +``` + +The `Yielded` variant indicates that the coroutine can later be resumed. This +corresponds to a `yield` point in a coroutine. The `Complete` variant indicates +that the coroutine is complete and cannot be resumed again. Calling `resume` +after a coroutine has returned `Complete` will likely result in a panic of the +program. + +### Closure-like semantics + +The closure-like syntax for coroutines alludes to the fact that they also have +closure-like semantics. Namely: + +* When created, a coroutine executes no code. A closure literal does not + actually execute any of the closure's code on construction, and similarly a + coroutine literal does not execute any code inside the coroutine when + constructed. + +* Coroutines can capture outer variables by reference or by move, and this can + be tweaked with the `move` keyword at the beginning of the closure. Like + closures all coroutines will have an implicit environment which is inferred by + the compiler. Outer variables can be moved into a coroutine for use as the + coroutine progresses. + +* Coroutine literals produce a value with a unique type which implements the + `std::ops::Coroutine` trait. This allows actual execution of the coroutine + through the `Coroutine::resume` method as well as also naming it in return + types and such. + +* Traits like `Send` and `Sync` are automatically implemented for a `Coroutine` + depending on the captured variables of the environment. Unlike closures, + coroutines also depend on variables live across suspension points. This means + that although the ambient environment may be `Send` or `Sync`, the coroutine + itself may not be due to internal variables live across `yield` points being + not-`Send` or not-`Sync`. Note that coroutines do + not implement traits like `Copy` or `Clone` automatically. + +* Whenever a coroutine is dropped it will drop all captured environment + variables. + +### Coroutines as state machines + +In the compiler, coroutines are currently compiled as state machines. Each +`yield` expression will correspond to a different state that stores all live +variables over that suspension point. Resumption of a coroutine will dispatch on +the current state and then execute internally until a `yield` is reached, at +which point all state is saved off in the coroutine and a value is returned. + +Let's take a look at an example to see what's going on here: + +```rust +#![feature(coroutines, coroutine_trait)] + +use std::ops::Coroutine; +use std::pin::Pin; + +fn main() { + let ret = "foo"; + let mut coroutine = move || { + yield 1; + return ret + }; + + Pin::new(&mut coroutine).resume(()); + Pin::new(&mut coroutine).resume(()); +} +``` + +This coroutine literal will compile down to something similar to: + +```rust +#![feature(arbitrary_self_types, coroutines, coroutine_trait)] + +use std::ops::{Coroutine, CoroutineState}; +use std::pin::Pin; + +fn main() { + let ret = "foo"; + let mut coroutine = { + enum __Coroutine { + Start(&'static str), + Yield1(&'static str), + Done, + } + + impl Coroutine for __Coroutine { + type Yield = i32; + type Return = &'static str; + + fn resume(mut self: Pin<&mut Self>, resume: ()) -> CoroutineState { + use std::mem; + match mem::replace(&mut *self, __Coroutine::Done) { + __Coroutine::Start(s) => { + *self = __Coroutine::Yield1(s); + CoroutineState::Yielded(1) + } + + __Coroutine::Yield1(s) => { + *self = __Coroutine::Done; + CoroutineState::Complete(s) + } + + __Coroutine::Done => { + panic!("coroutine resumed after completion") + } + } + } + } + + __Coroutine::Start(ret) + }; + + Pin::new(&mut coroutine).resume(()); + Pin::new(&mut coroutine).resume(()); +} +``` + +Notably here we can see that the compiler is generating a fresh type, +`__Coroutine` in this case. This type has a number of states (represented here +as an `enum`) corresponding to each of the conceptual states of the coroutine. +At the beginning we're closing over our outer variable `foo` and then that +variable is also live over the `yield` point, so it's stored in both states. + +When the coroutine starts it'll immediately yield 1, but it saves off its state +just before it does so indicating that it has reached the yield point. Upon +resuming again we'll execute the `return ret` which returns the `Complete` +state. + +Here we can also note that the `Done` state, if resumed, panics immediately as +it's invalid to resume a completed coroutine. It's also worth noting that this +is just a rough desugaring, not a normative specification for what the compiler +does. +"##, + }, + Lint { + label: "coverage_attribute", + description: r##"# `coverage_attribute` + +The tracking issue for this feature is: [#84605] + +[#84605]: https://github.com/rust-lang/rust/issues/84605 + +--- + +The `coverage` attribute can be used to selectively disable coverage +instrumentation in an annotated function.

In order to do this, the target will execute the ELF to +generate a receipt containing the output of the computation along with a +cryptographic seal. This receipt can be verified to ensure the integrity of the +computation and its result. This target is implemented as software only; it has +no hardware implementation. + +We have a cargo extension called [cargo-risczero] that allow users to generate +project templates, install tools for improved user experience, build the binary +using a docker environment and test programs. + +## Requirements + +The target only supports cross compilation and no host tools. The target +supports `alloc` with a default allocator and has experimental support for +`std`. The target expects the binaries to be in ELF. + +The target's execution environment is single threaded, non-preemptive, and does +not support any privileged instructions, nor unaligned accesses. At the time of +writing the VM has 192 MB of memory and text/data, heap, and stack need to be +with in the address range `0x400` - `0x0C000000`. The binaries themselves expect +no operating system and can be thought of as running on bare-metal. The target +does not use `#[target_feature(...)]` or `-C target-feature=` values. + +Calling `extern "C"` on the target uses the C calling convention outlined in the +[RISC-V specification]. + +## Building for the zkVM + +Programs for the zkVM could be built by adding it to the `target` list in +`config.toml`. However, we recommend building programs in our starter template +generated by the [cargo-risczero] utility and the [risc0-build] crate. This +crate calls `rustc` with `-C "link-arg=-Ttext=` so that it maps the text in the +appropriate location as well as generating variables that represent the ELF and +a unique ID associated with the ELF. The starter template provides developers +with system calls that are useful to zero knowledge computing such as writing to +the public output, hashing using sha256, and multiply big integers. + +## Building Rust programs + +Rust does not yet ship pre-compiled artifacts for this target. To compile for +this target, you will either need to build Rust with the target enabled (see +"Building the target" above). We do not recommend using `build-std` as we have +run into issues building core in the past on our starter template. An alternate +solution is to download the risc0 tool chain by running `cargo risczero install`. + +## Testing + +Note: the target is implemented as a software emulator called the zkVM and there +is no hardware implementation of the target. + +The most practical way to test the target program is to use our starter template +that can be generated by using the `cargo risczero new` command. The template +generates a sample "host" and "guest" code. The guest code compiled to the +target (which is RV32IM) whereas the "host" code is compiled to run on the +programmer's machine running either a Linux distribution or macOS.
