This commit makes the JSON emitter use `-Z terminal-width` in the "rendered" field of the JSON output. Signed-off-by: David Wood <david@davidtw.co>
…atch, r=oli-obk Stabilize `#![feature(const_if_match)]` Quoting from the [stabilization report](rust-lang#49146 (comment)): > `if` and `match` expressions as well as the short-circuiting logic operators `&&` and `||` will become legal in all [const contexts](https://doc.rust-lang.org/reference/const_eval.html#const-context). A const context is any of the following: > > - The initializer of a `const`, `static`, `static mut` or enum discriminant. > - The body of a `const fn`. > - The value of a const generic (nightly only). > - The length of an array type (`[u8; 3]`) or an array repeat expression (`[0u8; 3]`). > > Furthermore, the short-circuiting logic operators will no longer be lowered to their bitwise equivalents (`&` and `|` respectively) in `const` and `static` initializers (see rust-lang#57175). As a result, `let` bindings can be used alongside short-circuiting logic in those initializers. Resolves rust-lang#49146. Ideally, we would resolve 🐳 rust-lang#66753 before this lands on stable, so it might be worth pushing this back a release. Also, this means we should get the process started for rust-lang#52000, otherwise people will have no recourse except recursion for iterative `const fn`. r? @oli-obk
Added io forwarding methods to the stdio structs Added methods to forward the `io::Read` and `io::Write` methods of the myriad wrapper structs in `stdio.rs` to their underlying readers / writers. This is especially important for the structs on the outside of a locking boundary, to ensure that the lock isn't being dropped and re-acquired in a loop.
…Amanieu Add documentation to point to `File::open` or `OpenOptions::open` instead of `is_file` to check read/write possibility Fixes rust-lang#64170. This adds documentation to point user towards `!is_dir` instead of `is_file` when all they want to is read from a source. I ran `rg "fn is_file\("` to find all `is_file` methods, I hope I did not miss one.
Prepare for LLVM 11 These are just the code changes needed to build with the current LLVM master (version 11). r? @nikic
