Module core::mem [] [src]

Basic functions for dealing with memory

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

Functions

align_of

Returns the alignment in memory for a type.

align_of_val

Returns the alignment of the type of the value that _val`_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

Returns the ABI-required minimum alignment of a type

min_align_of_val

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

replace

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

size_of

Returns the size of a type in bytes.

size_of_val

Returns the size of the type that val`val` points to in bytes.

swap

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

transmute_copy

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

uninitialized

Creates an uninitialized value.

zeroed

Creates a value initialized to zero.

copy_lifetime [Unstable]

Transforms lifetime of the second pointer to match the first.

copy_mut_lifetime [Unstable]

Transforms lifetime of the second mutable pointer to match the first.

dropped [Unstable]

Creates a value initialized to an unspecified series of bytes.
