# 1.36.0[−][src]Struct std::task::RawWaker

    pub struct RawWaker { /* fields omitted */ }

A `RawWaker` allows the implementor of a task executor to create a `Waker` which provides customized wakeup behavior.

It consists of a data pointer and a virtual function pointer table (vtable) that customizes the behavior of the `RawWaker`.

## Methods

### `impl RawWaker`[src]

#### `pub const fn new(data: *const (), vtable: &'static RawWakerVTable) -> RawWaker`[src]

Creates a new `RawWaker` from the provided `data` pointer and `vtable`.

The `data` pointer can be used to store arbitrary data as required by the executor. This could be e.g. a type-erased pointer to an `Arc` that is associated with the task. The value of this pointer will get passed to all functions that are part of the `vtable` as the first parameter.

The `vtable` customizes the behavior of a `Waker` which gets created from a `RawWaker`. For each operation on the `Waker`, the associated function in the `vtable` of the underlying `RawWaker` will be called.
