Struct ScopeFifo

Source 
pub struct ScopeFifo<'scope> { /* private fields */ }
Expand description

Represents a fork-join scope which can be used to spawn any number of tasks. Those spawned from the same thread are prioritized in relative FIFO order. See scope_fifo() for more information.

Implementations§

Source§

impl<'scope> ScopeFifo<'scope>

Source

pub fn spawn_fifo<BODY>(&self, body: BODY)
where BODY: FnOnce(&ScopeFifo<'scope>) + Send + 'scope,

Spawns a job into the fork-join scope self. This job will execute sometime before the fork-join scope completes. The job is specified as a closure, and this closure receives its own reference to the scope self as argument. This can be used to inject new jobs into self.

§See also

This method is akin to Scope::spawn(), but with a FIFO priority. The scope_fifo function has more details about this distinction.

Source

pub fn spawn_broadcast<BODY>(&self, body: BODY)
where BODY: Fn(&ScopeFifo<'scope>, BroadcastContext<'_>) + Send + Sync + 'scope,

Spawns a job into every thread of the fork-join scope self. This job will execute on each thread sometime before the fork-join scope completes. The job is specified as a closure, and this closure receives its own reference to the scope self as argument, as well as a BroadcastContext.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
