Struct Scope 

pub struct Scope<'scope, 'env: 'scope> { /* private fields */ }

A scope to submit closures in.

See scope for details.

Implementations

impl<'scope, 'env> Scope<'scope, 'env>

pub fn submit<F: FnOnce() + Send + 'scope>(&'scope self, f: F)

Submits the closure to run on the Pool.

The closure cannot outlive the Scope it’s run in.

Methods from Deref<Target = Pool>

pub fn set_thread_limits(&self, min: u32, max: u32)

Sets the thread limits for the Pool object.

pub fn submit<F: FnOnce() + Send + 'static>(&self, f: F)

Submit the closure to the thread pool.

• The closure must have 'static lifetime as the thread may outlive the lifetime in which submit is called.
• The closure must be Send as it will be sent to another thread for execution.

pub fn scope<'env, F>(&self, f: F)

where F: for<'scope> FnOnce(&'scope Scope<'scope, 'env>),

Create a scope for submitting closures.

Within this scope local variables can be sent to the pool thread for execution. This is possible because scope will wait for all submitted closures to finish before returning, Note however that it will also wait for closures that were submitted from other threads.

pub fn join(&self)

Waits for all submissions to finish.

Dropping the Pool will also wait for all submissions to finish.

Trait Implementations

impl Deref for Scope<'_, '_>

type Target = Pool

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
