# [−][src]Module core::task

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

futures in libcore are unstable

Types and Traits for working with asynchronous tasks.

## Structs

Context | Experimental The `Context` of an asynchronous task.
RawWaker | Experimental A `RawWaker` allows the implementor of a task executor to create a `Waker` which provides customized wakeup behavior.
RawWakerVTable | Experimental A virtual function pointer table (vtable) that specifies the behavior of a `RawWaker`.
Waker | Experimental A `Waker` is a handle for waking up a task by notifying its executor that it is ready to be run.

## Enums

Poll | Experimental Indicates whether a value is available or if the current task has been scheduled to receive a wakeup instead.

## 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`)
