Stabilize `const_float_methods` Tracking issue: https://github.com/rust-lang/rust/issues/130843 Relnotes: #133383 Stabilized const API: ```rust // in `core` impl f32/f64 { pub const fn recip(self) -> Self; pub const fn to_degrees(self) -> Self; pub const fn to_radians(self) -> Self; pub const fn max(self, other: Self) -> Self; pub const fn min(self, other: Self) -> Self; pub const fn clamp(self, min: Self, max: Self) -> Self; pub const fn abs(self) -> Self; pub const fn signum(self) -> Self; pub const fn copysign(self, sign: Self) -> Self; } ``` Closes https://github.com/rust-lang/rust/issues/130843 r? libs-api cc `@RalfJung` -- I think the way const-stability attributes work have change a bit since the last time a wrote a const-stabilization PR, please make sure I got them right.
UI Tests
This folder contains rustc's
UI tests.
Test Directives (Headers)
Typically, a UI test will have some test directives / headers which are special comments that tell compiletest how to build and intepret a test.
As part of an on-going effort to rewrite compiletest
(see https://github.com/rust-lang/compiler-team/issues/536), a major
change proposal to change legacy compiletest-style headers // <directive>
to ui_test-style headers
//@ <directive> was accepted (see
https://github.com/rust-lang/compiler-team/issues/512.
An example directive is ignore-test. In legacy compiletest style, the header
would be written as
// ignore-test
but in ui_test style, the header would be written as
//@ ignore-test
compiletest is changed to accept only //@ directives for UI tests
(currently), and will reject and report an error if it encounters any
comments // <content> that may be parsed as an legacy compiletest-style
test header. To fix this, you should migrate to the ui_test-style header
//@ <content>.
