Macros
- type_ascribeExperimentalUnstable placeholder for type ascription.
Attribute Macros
- alloc_error_handlerExperimentalAttribute macro applied to a function to register it as a handler for allocation failure.
- benchExperimentalAttribute macro applied to a function to turn it into a benchmark test.
- cfg_accessibleExperimentalKeeps the item it’s applied to if the passed path is accessible, and removes it otherwise.
- cfg_evalExperimentalExpands all
#[cfg]
and#[cfg_attr]
attributes in the code fragment it’s applied to. - derive_constExperimentalAttribute macro used to apply derive macros for implementing traits in a const context.
- test_caseExperimentalAn implementation detail of the
#[test]
and#[bench]
macros. - Attribute macro used to apply derive macros.
- Attribute macro applied to a static to register it as a global allocator.
- Attribute macro applied to a function to turn it into a unit test.
Derive Macros
- RustcDecodableDeprecatedUnstable implementation detail of the
rustc
compiler, do not use. - RustcEncodableDeprecatedUnstable implementation detail of the
