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.

Constants

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.
