Module std::ptr

Raw, unsafe pointers, *const T, and *mut T.

See also the pointer primitive types.

Structs

NonNull	*mut T but non-zero and covariant.
Unique	[ Experimental ] A wrapper around a raw non-null *mut T that indicates that the possessor of this wrapper owns the referent. Useful for building abstractions like Box<T>, Vec<T>, String, and HashMap<K, V>.

Functions

copy⚠	Copies count * size_of<T> bytes from src to dst. The source and destination may overlap.
copy_nonoverlapping⚠	Copies count * size_of<T> bytes from src to dst. The source and destination may not overlap.
drop_in_place⚠	Executes the destructor (if any) of the pointed-to value.
eq	Compare raw pointers for equality.
null	Creates a null raw pointer.
null_mut	Creates a null mutable raw pointer.
read⚠	Reads the value from src without moving it. This leaves the memory in src unchanged.
read_unaligned⚠	Reads the value from src without moving it. This leaves the memory in src unchanged.
read_volatile⚠	Performs a volatile read of the value from src without moving it. This leaves the memory in src unchanged.
replace⚠	Replaces the value at dest with src, returning the old value, without dropping either.
swap⚠	Swaps the values at two mutable locations of the same type, without deinitializing either.
write⚠	Overwrites a memory location with the given value without reading or dropping the old value.
write_bytes⚠	Invokes memset on the specified pointer, setting count * size_of::<T>() bytes of memory starting at dst to val.
write_unaligned⚠	Overwrites a memory location with the given value without reading or dropping the old value.
write_volatile⚠	Performs a volatile write of a memory location with the given value without reading or dropping the old value.
swap_nonoverlapping⚠	[ Experimental ] Swaps a sequence of values at two mutable locations of the same type.
