# Module core::future[−][src]

🔬 This is a nightly-only experimental API. (`futures_api` #50547)

futures in libcore are unstable

Asynchronous values.

## Structs

FutureObj | [ Experimental ] A custom trait object for polling futures, roughly akin to `Box<dyn Future<Output = T> + Send + 'a>`.
LocalFutureObj | [ Experimental ] A custom trait object for polling futures, roughly akin to `Box<dyn Future<Output = T> + 'a>`.

## Traits

Future | [ Experimental ] A future represents an asychronous computation.
UnsafeFutureObj | [ Experimental ] A custom implementation of a future trait object for `FutureObj`, providing a hand-rolled vtable.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
