Context

Struct Context 

Source
pub struct Context<TTask> {
    pub Identifier: usize,
    pub Local: (Worker<TTask>, Worker<TTask>, Worker<TTask>),
    pub Share: Arc<Share<TTask>>,
}
Expand description

Contains all necessary components for a single worker thread to operate.

This includes the thread-local Worker deques, which are not safe to share, making this Context object the sole owner of a worker’s private queues.

Fields§

§Identifier: usize

A unique identifier for the worker, used to avoid self-stealing.

§Local: (Worker<TTask>, Worker<TTask>, Worker<TTask>)

Thread-local work queues for each priority level.

§Share: Arc<Share<TTask>>

A reference to the shared components of the entire queue system.

Implementations§

Source§

impl<TTask> Context<TTask>

Source

pub fn Next(&self) -> Option<TTask>

Finds the next available task for the worker to execute.

This method implements the complete work-finding logic:

  1. Check local deques (from high to low priority).
  2. If local deques are empty, attempt to steal from the system (from high to low priority).
Source

pub fn Steal<'a>( &self, Injector: &'a Injector<TTask>, Stealers: &'a [Stealer<TTask>], Local: &'a Worker<TTask>, ) -> Option<TTask>

Attempts to steal a task from a specific priority set.

It first tries to steal a batch from the global injector queue for that priority. If that fails, it attempts to steal from a randomly chosen peer worker to ensure fair distribution and avoid contention hotspots.
