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.
Implementations
impl RawWaker
pub const fn new(data: *const (), vtable: &'static RawWakerVTable) -> RawWaker
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.
