pub struct Scope<'scope, 'env, T>where
'env: 'scope,{ /* private fields */ }Expand description
A TaskPool scope for running one or more non-'static futures.
For more information, see TaskPool::scope.
Implementations§
source§impl<'scope, 'env, T> Scope<'scope, 'env, T>where
T: Send + 'env,
impl<'scope, 'env, T> Scope<'scope, 'env, T>where
T: Send + 'env,
sourcepub fn spawn<Fut>(&self, f: Fut)where
Fut: Future<Output = T> + 'scope,
pub fn spawn<Fut>(&self, f: Fut)where
Fut: Future<Output = T> + 'scope,
Spawns a scoped future onto the executor. The scope must outlive
the provided future. The results of the future will be returned as a part of
TaskPool::scope’s return value.
On the single threaded task pool, it just calls Scope::spawn_on_scope.
For more information, see TaskPool::scope.
sourcepub fn spawn_on_external<Fut>(&self, f: Fut)where
Fut: Future<Output = T> + 'scope,
pub fn spawn_on_external<Fut>(&self, f: Fut)where
Fut: Future<Output = T> + 'scope,
Spawns a scoped future onto the executor. The scope must outlive
the provided future. The results of the future will be returned as a part of
TaskPool::scope’s return value.
On the single threaded task pool, it just calls Scope::spawn_on_scope.

sourcepub fn spawn_on_scope<Fut>(&self, f: Fut)where
Fut: Future<Output = T> + 'scope,
pub fn spawn_on_scope<Fut>(&self, f: Fut)where
Fut: Future<Output = T> + 'scope,
Spawns a scoped future that runs on the thread the scope called from. The
scope must outlive the provided future. The results of the future will be
returned as a part of TaskPool::scope’s return value.
