Struct eager_futures::Eager

pub struct Eager<'a, T>(pub Rc<RefCell<StateAndData<'a, T, dyn Any + 'a>>>);

An eager future representing an asynchronous value.

Implementations

impl<'a, T> Eager<'a, T>

pub fn new() -> Self

Create a new eager future. Intended to be used by I/O operation implementers.

pub fn set_no_handler(&self)

Setup the eager future so that when it completes, discard the result and do nothing.

pub fn set_handler(&self, handler: impl FnOnce(T) + 'a)

Setup the eager future so that when it completes, call the supplied handler.

pub fn on_complete(&self, result: T)

Complete the eager future. Intended to be used by I/O operation implementers.

pub fn map<To, F>(&self, func: F) -> Eager<'a, To> where
    To: 'a,
    F: FnOnce(T) -> To + 'a, 

Transform the result of this eager future by the computation defined by func.

pub fn then<To, F>(&self, func: F) -> Eager<'a, To> where
    To: 'a,
    F: FnOnce(T) -> Eager<'a, To> + 'a, 

Chain another operation defined by func after this eager future completes.

Trait Implementations

impl<'a, T> Clone for Eager<'a, T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.
