Struct LocalSpawner

pub struct LocalSpawner { /* private fields */ }

A handle to a LocalPool that implements Spawn and LocalSpawn.

Implementations

impl LocalSpawner

pub fn enter<F, T>(self, enter: &mut Enter, f: F) -> T

where F: FnOnce(&mut Enter) -> T,

Enter a spawner.

Clears the current spawner when f returns.

current_local needs this to work.

A runtime (combining reactor, pool, …) should enter a spawner handle (in each thread it runs tasks from the pool) so all tasks have access to the spawner.

Panics

Panics if a spawner is already entered.
