Module nom::lib::std::mem1.0.0[−][src]

Basic functions for dealing with memory.

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

Structs

Discriminant	Opaque type representing the discriminant of an enum.
Pin	[ Experimental ] A pinned reference.

align_of	Returns the ABI-required minimum alignment of a type.
align_of_val	Returns the ABI-required minimum alignment of the type of the value that `val` points to.
discriminant	Returns a value uniquely identifying the enum variant in `v`.
drop	Disposes of a value.
forget	Leaks a value: takes ownership and "forgets" about the value without 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.
needs_drop	Returns whether dropping values of type `T` matters.
replace	Replaces the value at a mutable location with a new one, returning the old value, without deinitializing either one.
size_of	Returns the size of a type in bytes.
size_of_val	Returns the size of the pointed-to value in bytes.
swap	Swaps the values at two mutable locations, without deinitializing either one.
transmute ^⚠	Reinterprets the bits of a value of one type as another type.
transmute_copy ^⚠	Interprets `src` as having type `&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 whose bytes are all zero.

A wrapper to inhibit compiler from automatically calling T’s destructor.
