Injector

Struct Injector 

Source
pub struct Injector<T> { /* private fields */ }
Expand description

An injector queue.

This is a FIFO queue that can be shared among multiple threads. Task schedulers typically have a single injector queue, which is the entry point for new tasks.

Implementations§

Source§

impl<T> Injector<T>

Source

pub fn new() -> Self

Creates a new injector queue.

Source

pub fn push(&self, task: T)

Pushes a task into the queue.

Source

pub fn steal(&self) -> Steal<T>

Steals a task from the queue.

Source

pub fn steal_batch(&self, dest: &Worker<T>) -> Steal<()>

Steals a batch of tasks and pushes them into a worker.

How many tasks exactly will be stolen is not specified. That said, this method will try to steal around half of the tasks in the queue, but also not more than some constant limit.

Source

pub fn steal_batch_and_pop(&self, dest: &Worker<T>) -> Steal<T>

Steals a batch of tasks, pushes them into a worker, and pops a task from that worker.

How many tasks exactly will be stolen is not specified. That said, this method will try to steal around half of the tasks in the queue, but also not more than some constant limit.

Source

pub fn is_empty(&self) -> bool

Returns true if the queue is empty.
