Fixes time.rs by updating the MIN and MAX structs appropriately. Signed-off-by: John Nunley <dev@notgull.net>
Start small. If it works well we can increase usage bit by bit as time passes. Note that we keep using "0" to represent "no specific line" because changing to `Option<LineNumber>` everywhere is much bigger and noisier change. That can be done later if wanted.
* No method named `allow_toggle()` exists on the type, but based on the documentation of both `requires_nightly()` and `toggle_allowed()` it seems that `toggle_allowed()` is the intended method to mention. * Add `()` to the mention of `in_cfg()` to make it clear that a method is being referred to, and to match the presence of `()` in the mention of `toggle_allowed()`.
…t-impl, r=petrochenkov Support syntax for one-line trait reuse This PR adds support for reusing the whole trait with a one-line reuse syntax and is part of the delegation feature rust-lang#118212: ```rust trait T { fn foo(&self); } struct S; impl T for S { ... } struct Wrapper(S); reuse impl T for Wrapper { self.0 } ``` The core idea is that we already have support for glob reuse, so in this scenario we want to transform one-line reuse into a trait impl block with a glob reuse in the following way: ```rust //Before reuse impl T for Wrapper { self.0 } //After impl T for Wrapper { reuse T::* { self.0 } } ``` It seems like this task can be solved during parsing stage, when we encountered a one-line trait reuse, we can expand into this impl block right away, and the code which was already written to expand glob delegations will take care about the rest. We will copy trait path into glob reuse path. The implementation of the transformation reuses already existing methods for `impl` parsing, however, we do not parse inner `impl` items, instead we parse "inner items" as delegation body. Thus, we do not have to deal with generics, consts, unsafe and other `impl` related features. Other syntax possibility is trying to shorten one-line reuse by replacing `impl` keyword with `reuse` keyword: ```rust reuse T for Wrapper { self.0 } ``` In this case implementation may become more complicated, and the syntax more confusing, as keywords such as `const` or `unsafe` will precede `reuse`, and there are also generics: ```rust unsafe reuse<T1, T2> T for Wrapper { self.0 } ``` In the first (currently implemented) version reuse is placed in the beginning of the item, and it is clear that we will reuse trait implementation, while in the second, shorter version, the `reuse` keyword may be lost in generics and keywords that may precede `impl`. r? ``@petrochenkov``
compiletest: Add `LineNumber` newtype to avoid `+1` magic here and there Start small. If it works well we can increase usage bit by bit as time passes. My main motivation for doing this is to get rid of the `+ 1` I otherwise have to add in rust-lang#150201 on this line: ```rs crate::directives::line::line_directive(file, zero_based_line_no + 1, &line) ``` But I think this is a nice general improvement by itself. Note that we keep using "0" to represent "no specific line" because changing to `Option<LineNumber>` everywhere is a very noisy and significant change. That _can_ be changed later if wanted, but let's not do it now.

…boet std: remove unsupported pipe module from VEXos pal rust-lang#146794 moved `pipe` implementations out of PAL and into a toplevel `sys` module. While most targets supporting libstd were updated, the PR did not remove the old module from the `vexos` PAL, causing builds to fail on the `armv7a-vex-v5` target. <img width="2258" height="322" alt="image" src="https://github.com/user-attachments/assets/3bdb83f9-e577-4795-9d20-0ae4ab5d505c" /> This PR removes the old module path in the PAL and allows `vexos` targets to fall back to the `unsupported` implementation in sys/pipe.
…lcnr `target_features::Stability`: tweak docs of `requires_nightly()` * No method named `allow_toggle()` exists on the type, but based on the documentation of both `requires_nightly()` and `toggle_allowed()` it seems that `toggle_allowed()` is the intended method to mention. * Add `()` to the mention of `in_cfg()` to make it clear that a method is being referred to, and to match the presence of `()` in the mention of `toggle_allowed()`.
