## IdleState

# Struct IdleState

Source

    pub(crate) struct IdleState {
        worker_index: usize,
        rounds: u32,
        jobs_counter: JobsEventCounter,
    }

Expand description

An instance of this struct is created when a thread becomes idle. It is consumed when the thread finds work, and passed by `&mut` reference for operations that preserve the idle state. (In other words, producing one of these structs is evidence the thread is idle.) It tracks state such as how long the thread has been idle.

## Fields§

§`worker_index: usize`

What is worker index of the idle thread?

§`rounds: u32`

How many rounds have we been circling without sleeping?

§`jobs_counter: JobsEventCounter`

Once we become sleepy, what was the sleepy counter value? Set to `INVALID_SLEEPY_COUNTER` otherwise.

## Layout§

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.
