Struct pawawwewism::Promise

pub struct Promise<T> { /* private fields */ }

An empty slot that can be filled with a T, fulfilling the promise.

Fulfilling a Promise lets the connected PromiseHandle retrieve the value. A connected pair of Promise and PromiseHandle can be created by calling promise.

Implementations

impl<T> Promise<T>

pub fn fulfill(self, value: T)

Fulfills the promise with a value, consuming it.

If a thread is currently waiting at PromiseHandle::block, it will be woken up.

This method does not block or fail. If the connected PromiseHandle was dropped, value will be dropped and nothing happens. The calling thread is expected to exit when it attempts to obtain a new Promise to fulfill.

Trait Implementations

impl<T> Drop for Promise<T>

fn drop(&mut self)

Executes the destructor for this type.
