Structs

Shared [
Experimental
]

A wrapper around a raw non-null *mut T that indicates that the possessor of this wrapper has shared ownership of the referent. Useful for building abstractions like Rc<T> or Arc<T>, which internally use raw pointers to manage the memory that they own.
Unique [
Experimental
]

A wrapper around a raw non-null *mut T that indicates that the possessor of this wrapper owns the referent. This in turn implies that the Unique<T> is Send/Sync if T is Send/Sync, unlike a raw *mut T (which conveys no particular ownership semantics). It also implies that the referent of the pointer should not be modified without a unique path to the Unique reference. Useful for building abstractions like Vec<T> or Box<T>, which internally use raw pointers to manage the memory that they own.

Functions

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. They may overlap, unlike mem::swap which is otherwise equivalent.
write⚠

Overwrites a memory location with the given value without reading or dropping the old value.
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.
