# Macro futures::task_local [−] [src]

    macro_rules! task_local {
        (static $NAME:ident: $t:ty = $e:expr) => { ... };
    }

A macro to create a `static` of type `LocalKey`

This macro is intentionally similar to the `thread_local!`, and creates a `static` which has a `with` method to access the data on a task.

The data associated with each task local is per-task, so different tasks will contain different values.

## 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`)
