pub struct Task<T> { /* private fields */ }
Expand description
A set of concurrent actions to be performed by the iced runtime.
A Task
may produce a bunch of values of type T
.

impl<T> Task<T>
Sourcepub fn done(value: T) -> Task<T>where
T: MaybeSend + 'static,
pub fn done(value: T) -> Task<T>where

that instantly produces the given value.
Sourcepub fn perform<A>(
future: impl Future<Output = A> + MaybeSend + 'static,
f: impl FnOnce(A) -> T + MaybeSend + 'static,
) -> Task<T>where
T: MaybeSend + 'static,

pub fn perform<A>(
future: impl Future<Output = A> + MaybeSend + 'static,
f: impl FnOnce(A) -> T + MaybeSend + 'static,
) -> Task<T>where
T: MaybeSend + 'static,
A: MaybeSend + 'static,
Sourcepub fn run<A>(
stream: impl Stream<Item = A> + MaybeSend + 'static,
f: impl Fn(A) -> T + MaybeSend + 'static,
) -> Task<T>where
T: 'static,
pub fn run<A>(
stream: impl Stream<Item = A> + MaybeSend + 'static,
f: impl Fn(A) -> T + MaybeSend + 'static,
) -> Task<T>where
T: 'static,
Creates a Task
that runs the given [Stream
] to completion and maps each
item with the given closure.
Sourcepub fn sip<S>(
sipper: S,
on_progress: impl FnMut(<S as Core>::Progress) -> T + MaybeSend + 'static,
on_output: impl FnOnce(<S as Future>::Output) -> T + MaybeSend + 'static,

T: MaybeSend + 'static,
pub fn sip<S>(
sipper: S,
on_progress: impl FnMut(<S as Core>::Progress) -> T + MaybeSend + 'static,

Sourcepub fn batch(tasks: impl IntoIterator<Item = Task<T>>) -> Task<T>where
T: 'static,
pub fn batch(tasks: impl IntoIterator<Item = Task<T>>) -> Task<T>where
T: 'static,
Combines the given tasks and produces a single Task
that will run all of them
in parallel.
Sourcepub fn map<O>(self, f: impl FnMut(T) -> O + MaybeSend + 'static) -> Task<O>where
T: MaybeSend + 'static,
O: MaybeSend + 'static,
pub fn map<O>(self, f: impl FnMut(T) -> O + MaybeSend + 'static) -> Task<O>where
T: MaybeSend + 'static,
O: MaybeSend + 'static,
Maps the output of a Task
with the given closure.
Sourcepub fn then<O>(
self,
f: impl FnMut(T) -> Task<O> + MaybeSend + 'static,
) -> Task<O>where
T: MaybeSend + 'static,
O: MaybeSend + 'static,

self,
f: impl FnMut(T) -> Task<O> + MaybeSend + 'static,
) -> Task<O>where
T: MaybeSend + 'static,
O: MaybeSend + 'static,
Sourcepub fn chain(self, task: Task<T>) -> Task<T>where
T: 'static,
pub fn chain(self, task: Task<T>) -> Task<T>where
T: 'static,
Chains a new Task
to be performed once the current one finishes completely.
Sourcepub fn future(future: impl Future<Output = T> + MaybeSend + 'static) -> Task<T>where
T: 'static,
pub fn future(future: impl Future<Output = T> + MaybeSend + 'static) -> Task<T>where
