Module cache

🔬This is a nightly-only experimental API. (stdarch_internal)

Caches run-time feature detection so that it only needs to be computed once.

Structs

Cache 🔒 Experimental

Feature cache with capacity for size_of::<usize>() * 8 - 1 features.

Initializer 🔒 Experimental

This type is used to initialize the cache

Constants

CACHE_CAPACITY 🔒 Experimental

Maximum number of features that can be cached.

Statics

CACHE 🔒 Experimental

This global variable is a cache of the features supported by the CPU.

Functions

detect_and_initialize 🔒 Experimental

initialize 🔒 Experimental

set_bit 🔒 Experimental

Sets the bit of x.

test 🔒 Experimental

Tests the bit of the storage. If the storage has not been initialized, initializes it with the result of os::detect_features().

test_bit 🔒 Experimental

Tests the bit of x.

unset_bit 🔒 Experimental

Unset the bit of x`.
