Macros§
- deref
Experimental Unstable placeholder for deref patterns. - type_
ascribe Experimental Unstable placeholder for type ascription.
Attribute Macros§
- alloc_
error_ handler Experimental Attribute macro applied to a function to register it as a handler for allocation failure. - bench
Experimental Attribute macro applied to a function to turn it into a benchmark test. - cfg_
accessible Experimental Keeps the item it’s applied to if the passed path is accessible, and removes it otherwise. - cfg_
eval Experimental Expands all#[cfg]and#[cfg_attr]attributes in the code fragment it’s applied to. - derive
Experimental Attribute macro used to apply derive macros. - derive_
const Experimental Attribute macro used to apply derive macros for implementing traits in a const context. - global_
allocator Experimental Attribute macro applied to a static to register it as a global allocator. - test
Experimental Attribute macro applied to a function to turn it into a unit test. - test_
case Experimental An implementation detail of the#[test]and#[bench]macros.
