Stabilization reportFeature name: Implemented in #52923 (v1) and #55884 (v2) and landed 4.5 and 1.5 months ago respectively. What is being stabilizedIf import path resolves without errors, then it's resolved in exactly same way as a non-import path. Possible extra errors (e.g. ambiguities) in import paths compared to other paths are caused by the fact that import paths are resolved early, when module structure of the crate is still in flux. Right now an ambiguity error is reported if the number of different candidates in scope for the first import segment ( struct S; // Candidate 1
fn main() {
use self::S; // Candidate 2
{
use self::S; // Candidate 3
use S as _; // Not an error
}
} Known issuesKnown deviations of macro paths and 2018 import paths from the "uniform path" model |

I've been meaning to read this and the other issues / descriptions you wrote but I've been a bit pressed for time. Would you mind waiting a bit (~a day) before I start FCP? |

Tests, and from what I can see implementation, looks good.

~A day later...
This seems like the right incremental balance for the time being. 👍 All in all, let's: @rfcbot merge
These 2 holes seem quite pathological... but how much work work would it be to fix them? |
Team member @Centril has proposed to merge this. The next step is review by the rest of the tagged teams:
No concerns currently listed. Once a majority of reviewers approve (and none object), this will enter its final comment period. If you spot a major issue that hasn't been raised at any point in this process, please speak up! See this document for info about what commands tagged team members can give me. |
The first one is relatively hard, but it only affects macros, not imports. |
I have a question: From the comments, it seemed like there was some "concern" about stabilizing this in time for the next release, is there any particular reason for that urgency? |
(Not saying I'm opposed, just asking) |

Stabilize `uniform_paths` Address all the things described in #56417. Assign visibilities to `macro_rules` items - `pub` to `macro_export`-ed macros and `pub(crate)` to non-exported macros, these visibilities determine how far these macros can be reexported with `use`. Prohibit use of reexported inert attributes and "tool modules", after renaming (e.g. `use inline as imported_inline`) their respective tools and even compiler passes won't be able to recognize and properly check them. Also turn use of uniform paths in 2015 macros into an error, I'd prefer to neither remove nor stabilize them right away because I still want to make some experiments in this area (uniform path fallback was added to 2015 macros used on 2018 edition in #56053 (comment)). UPDATE: The last commit also stabilizes the feature `uniform_paths`. Closes #53130 Closes #55618 Closes #56326 Closes #56398 Closes #56417 Closes #56821 Closes #57252 Closes #57422

Changelog: Version 1.32.0 (2019-01-17) ========================== Language -------- #### 2018 edition - [You can now use the `?` operator in macro definitions.][56245] The `?` operator allows you to specify zero or one repetitions similar to the `*` and `+` operators. - [Module paths with no leading keyword like `super`, `self`, or `crate`, will now always resolve to the item (`enum`, `struct`, etc.) available in the module if present, before resolving to a external crate or an item the prelude.][56759] E.g. ```rust enum Color { Red, Green, Blue } use Color::*; ``` #### All editions - [You can now match against `PhantomData<T>` types.][55837] - [You can now match against literals in macros with the `literal` specifier.][56072] This will match against a literal of any type. E.g. `1`, `'A'`, `"Hello World"` - [Self can now be used as a constructor and pattern for unit and tuple structs.][56365] E.g. ```rust struct Point(i32, i32); impl Point { pub fn new(x: i32, y: i32) -> Self { Self(x, y) } pub fn is_origin(&self) -> bool { match self { Self(0, 0) => true, _ => false, } } } ``` - [Self can also now be used in type definitions.][56366] E.g. ```rust enum List<T> where Self: PartialOrd<Self> // can write `Self` instead of `List<T>` { Nil, Cons(T, Box<Self>) // likewise here } ``` - [You can now mark traits with `#[must_use]`.][55663] This provides a warning if a `impl Trait` or `dyn Trait` is returned and unused in the program. Compiler -------- - [The default allocator has changed from jemalloc to the default allocator on your system.][55238] The compiler itself on Linux & macOS will still use jemalloc, but programs compiled with it will use the system allocator. - [Added the `aarch64-pc-windows-msvc` target.][55702] Libraries --------- - [`PathBuf` now implements `FromStr`.][55148] - [`Box<[T]>` now implements `FromIterator<T>`.][55843] - [The `dbg!` macro has been stabilized.][56395] This macro enables you to easily debug expressions in your rust program. E.g. ```rust let a = 2; let b = dbg!(a * 2) + 1; // ^-- prints: [src/main.rs:4] a * 2 = 4 assert_eq!(b, 5); ``` The following APIs are now `const` functions and can be used in a `const` context. - [`Cell::as_ptr`] - [`UnsafeCell::get`] - [`char::is_ascii`] - [`iter::empty`] - [`ManuallyDrop::new`] - [`ManuallyDrop::into_inner`] - [`RangeInclusive::start`] - [`RangeInclusive::end`] - [`NonNull::as_ptr`] - [`slice::as_ptr`] - [`str::as_ptr`] - [`Duration::as_secs`] - [`Duration::subsec_millis`] - [`Duration::subsec_micros`] - [`Duration::subsec_nanos`] - [`CStr::as_ptr`] - [`Ipv4Addr::is_unspecified`] - [`Ipv6Addr::new`] - [`Ipv6Addr::octets`] Stabilized APIs --------------- - [`i8::to_be_bytes`] - [`i8::to_le_bytes`] - [`i8::to_ne_bytes`] - [`i8::from_be_bytes`] - [`i8::from_le_bytes`] - [`i8::from_ne_bytes`] - [`i16::to_be_bytes`] - [`i16::to_le_bytes`] - [`i16::to_ne_bytes`] - [`i16::from_be_bytes`] - [`i16::from_le_bytes`] - [`i16::from_ne_bytes`] - [`i32::to_be_bytes`] - [`i32::to_le_bytes`] - [`i32::to_ne_bytes`] - [`i32::from_be_bytes`] - [`i32::from_le_bytes`] - [`i32::from_ne_bytes`] - [`i64::to_be_bytes`] - [`i64::to_le_bytes`] - [`i64::to_ne_bytes`] - [`i64::from_be_bytes`] - [`i64::from_le_bytes`] - [`i64::from_ne_bytes`] - [`i128::to_be_bytes`] - [`i128::to_le_bytes`] - [`i128::to_ne_bytes`] - [`i128::from_be_bytes`] - [`i128::from_le_bytes`] - [`i128::from_ne_bytes`] - [`isize::to_be_bytes`] - [`isize::to_le_bytes`] - [`isize::to_ne_bytes`] - [`isize::from_be_bytes`] - [`isize::from_le_bytes`] - [`isize::from_ne_bytes`] - [`u8::to_be_bytes`] - [`u8::to_le_bytes`] - [`u8::to_ne_bytes`] - [`u8::from_be_bytes`] - [`u8::from_le_bytes`] - [`u8::from_ne_bytes`] - [`u16::to_be_bytes`] - [`u16::to_le_bytes`] - [`u16::to_ne_bytes`] - [`u16::from_be_bytes`] - [`u16::from_le_bytes`] - [`u16::from_ne_bytes`] - [`u32::to_be_bytes`] - [`u32::to_le_bytes`] - [`u32::to_ne_bytes`] - [`u32::from_be_bytes`] - [`u32::from_le_bytes`] - [`u32::from_ne_bytes`] - [`u64::to_be_bytes`] - [`u64::to_le_bytes`] - [`u64::to_ne_bytes`] - [`u64::from_be_bytes`] - [`u64::from_le_bytes`] - [`u64::from_ne_bytes`] - [`u128::to_be_bytes`] - [`u128::to_le_bytes`] - [`u128::to_ne_bytes`] - [`u128::from_be_bytes`] - [`u128::from_le_bytes`] - [`u128::from_ne_bytes`] - [`usize::to_be_bytes`] - [`usize::to_le_bytes`] - [`usize::to_ne_bytes`] - [`usize::from_be_bytes`] - [`usize::from_le_bytes`] - [`usize::from_ne_bytes`] Cargo ----- - [You can now run `cargo c` as an alias for `cargo check`.][cargo/6218] - [Usernames are now allowed in alt registry URLs.][cargo/6242] Misc ---- - [`libproc_macro` has been added to the `rust-src` distribution.][55280] Compatibility Notes ------------------- - [The argument types for AVX's `_mm256_stream_si256`, `_mm256_stream_pd`, `_mm256_stream_ps`][55610] have been changed from `*const` to `*mut` as the previous implementation was unsound.

E.g. ```rust let a = 2; let b = dbg!(a * 2) + 1; // ^-- prints: [src/main.rs:4] a * 2 = 4 assert_eq!(b, 5); ``` The following APIs are now `const` functions and can be used in a `const` context. - [`Cell::as_ptr`] - [`UnsafeCell::get`] - [`char::is_ascii`] - [`iter::empty`] - [`ManuallyDrop::new`] - [`ManuallyDrop::into_inner`] - [`RangeInclusive::start`] - [`RangeInclusive::end`] - [`NonNull::as_ptr`] - [`slice::as_ptr`] - [`str::as_ptr`] - [`Duration::as_secs`] - [`Duration::subsec_millis`] - [`Duration::subsec_micros`] - [`Duration::subsec_nanos`] - [`CStr::as_ptr`] - [`Ipv4Addr::is_unspecified`] - [`Ipv6Addr::new`] - [`Ipv6Addr::octets`] Stabilized APIs --------------- - [`i8::to_be_bytes`] - [`i8::to_le_bytes`] - [`i8::to_ne_bytes`] - [`i8::from_be_bytes`] - [`i8::from_le_bytes`] - [`i8::from_ne_bytes`] - [`i16::to_be_bytes`] - [`i16::to_le_bytes`] - [`i16::to_ne_bytes`] - [`i16::from_be_bytes`] - [`i16::from_le_bytes`] - [`i16::from_ne_bytes`] - [`i32::to_be_bytes`] - [`i32::to_le_bytes`] - [`i32::to_ne_bytes`] - [`i32::from_be_bytes`] - [`i32::from_le_bytes`] - [`i32::from_ne_bytes`] - [`i64::to_be_bytes`] - [`i64::to_le_bytes`] - [`i64::to_ne_bytes`] - [`i64::from_be_bytes`] - [`i64::from_le_bytes`] - [`i64::from_ne_bytes`] - [`i128::to_be_bytes`] - [`i128::to_le_bytes`] - [`i128::to_ne_bytes`] - [`i128::from_be_bytes`] - [`i128::from_le_bytes`] - [`i128::from_ne_bytes`] - [`isize::to_be_bytes`] - [`isize::to_le_bytes`] - [`isize::to_ne_bytes`] - [`isize::from_be_bytes`] - [`isize::from_le_bytes`] - [`isize::from_ne_bytes`] - [`u8::to_be_bytes`] - [`u8::to_le_bytes`] - [`u8::to_ne_bytes`] - [`u8::from_be_bytes`] - [`u8::from_le_bytes`] - [`u8::from_ne_bytes`] - [`u16::to_be_bytes`] - [`u16::to_le_bytes`] - [`u16::to_ne_bytes`] - [`u16::from_be_bytes`] - [`u16::from_le_bytes`] - [`u16::from_ne_bytes`] - [`u32::to_be_bytes`] - [`u32::to_le_bytes`] - [`u32::to_ne_bytes`] - [`u32::from_be_bytes`] - [`u32::from_le_bytes`] - [`u32::from_ne_bytes`] - [`u64::to_be_bytes`] - [`u64::to_le_bytes`] - [`u64::to_ne_bytes`] - [`u64::from_be_bytes`] - [`u64::from_le_bytes`] - [`u64::from_ne_bytes`] - [`u128::to_be_bytes`] - [`u128::to_le_bytes`] - [`u128::to_ne_bytes`] - [`u128::from_be_bytes`] - [`u128::from_le_bytes`] - [`u128::from_ne_bytes`] - [`usize::to_be_bytes`] - [`usize::to_le_bytes`] - [`usize::to_ne_bytes`] - [`usize::from_be_bytes`] - [`usize::from_le_bytes`] - [`usize::from_ne_bytes`] Cargo ----- - [You can now run `cargo c` as an alias for `cargo check`.][cargo/6218] - [Usernames are now allowed in alt registry URLs.][cargo/6242] Misc ---- - [`libproc_macro` has been added to the `rust-src` distribution.][55280] Compatibility Notes ------------------- - [The argument types for AVX's `_mm256_stream_si256`, `_mm256_stream_pd`, `_mm256_stream_ps`][55610] have been changed from `*const` to `*mut` as the previous implementation was unsound.

Address all the things described in #56417.
Assign visibilities to
macro_rules
items -pub
tomacro_export
-ed macros andpub(crate)
to non-exported macros, these visibilities determine how far these macros can be reexported withuse
.Prohibit use of reexported inert attributes and "tool modules", after renaming (e.g.
use inline as imported_inline
) their respective tools and even compiler passes won't be able to recognize and properly check them.Also turn use of uniform paths in 2015 macros into an error, I'd prefer to neither remove nor stabilize them right away because I still want to make some experiments in this area (uniform path fallback was added to 2015 macros used on 2018 edition in #56053 (comment)).
UPDATE: The last commit also stabilizes the feature
