Modules

iter

Composable external iteration.

mem

Basic functions for dealing with memory.

Macros

format

Creates a String using interpolation of runtime expressions.

Structs

Arc

A thread-safe reference-counting pointer. ‘Arc’ stands for ‘Atomically Reference Counted’.

Box

A pointer type that uniquely owns a heap allocation of type T.

Mutex

A futures-aware mutex.

Pin

A pointer which pins its pointee in place.

Vec

A contiguous growable array type, written as Vec<T>, short for ‘vector’.

Traits

Future

A future represents an asynchronous computation, commonly obtained by use of async.

IntoIterator

Conversion into an Iterator.

Iterator

A trait for dealing with iterators.

Type Aliases

Map

NonZeroUsize

A usize that is known not to equal zero.
