# [−][src]Function alloc::task::local_waker

    pub unsafe fn local_waker<W: Wake + 'static>(wake: Arc<W>) -> LocalWaker

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

futures in libcore are unstable

Creates a `LocalWaker` from a local `wake`.

This function requires that `wake` is "local" (created on the current thread). The resulting `LocalWaker` will call `wake.wake_local()` when awoken, and will call `wake.wake()` if awoken after being converted to a `Waker`.

## 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`)
