Module std::mem [] [src]

Basic functions for dealing with memory

This module contains functions for querying the size and alignment of types, initializing and manipulating memory.

POST_DROP_USIZE [Unstable]

Functions

align_of

Returns the alignment in memory for a type.

align_of_val

Returns the ABI-required minimum alignment of the type of the value that val points to

drop

Disposes of a value.

forget

Leaks a value into the void, consuming ownership and never running its destructor.

min_align_of [Deprecated]

Returns the ABI-required minimum alignment of a type

min_align_of_val [Deprecated]

Returns the ABI-required minimum alignment of the type of the value that val points to

replace

Replaces the value at a mutable location with a new one, returning the old value, without deinitializing or copying either one.

size_of

Returns the size of a type in bytes.

size_of_val

Returns the size of the given value in bytes.

swap

Swap the values at two mutable locations of the same type, without deinitializing or copying either one.

transmute

Unsafely transforms a value of one type into a value of another type.

transmute_copy

Interprets src as &U, and then reads src without moving the contained value.

uninitialized

Bypasses Rust's normal memory-initialization checks by pretending to produce a value of type T, while doing nothing at all.

zeroed

Creates a value initialized to zero.

dropped [Unstable]

Creates a value initialized to an unspecified series of bytes.
