Macros

derefExperimental

Unstable placeholder for deref patterns.

type_ascribeExperimental

Unstable placeholder for type ascription.

Attribute Macros

global_allocator

Attribute macro applied to a static to register it as a global allocator.

test

Attribute macro applied to a function to turn it into a unit test.

alloc_error_handlerExperimental

Attribute macro applied to a function to register it as a handler for allocation failure.

benchExperimental

Attribute macro applied to a function to turn it into a benchmark test.

cfg_accessibleExperimental

Keeps the item it’s applied to if the passed path is accessible, and removes it otherwise.

cfg_evalExperimental

Expands all #[cfg] and #[cfg_attr] attributes in the code fragment it’s applied to.

define_opaqueExperimental

Provide a list of type aliases and other opaque-type-containing type definitions to an item with a body. This list will be used in that body to define opaque types’ hidden types. Can only be applied to things that have bodies.

derive_constExperimental

Attribute macro used to apply derive macros for implementing traits in a const context.

eiiExperimental

Externally Implementable Item: Defines an attribute macro that can override the item this is applied to.

eii_declarationExperimental

Impl detail of EII

test_caseExperimental

An implementation detail of the #[test] and #[bench] macros.

unsafe_eiiExperimental

Unsafely Externally Implementable Item: Defines an unsafe attribute macro that can override the item this is applied to.
