Methods

impl<T: Send + 'static> Promise<T>

fn new() -> (Promiser<T>, Promisee<T>)

fn clone(&self) -> Promise<T>

fn deliver(&self, d: T) -> bool

fn _with<W, F: FnMut(&T) -> W>(&self, f: F) -> Result<W, String>

should be called only from promiser/promisee-- public for now tho

fn destroy(&self) -> Result<String, String>

impl<T: Clone + Send + 'static> Clone for Promise<T>

fn clone(&self) -> Promise<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

impl<T: Send> Send for Promise<T>

impl<T: Sync + Send> Sync for Promise<T>

impl<T: Send + 'static> Drop for Promise<T>

Special Drop for Promise we don't want to hang readers on a local panic

fn drop(&mut self)
