Struct ThreadpoolDriver

pub struct ThreadpoolDriver { /* private fields */ }

A driver for AffinitizedThreadpool that is targeted at a specific CPU.

Implementations

impl ThreadpoolDriver

pub fn target_cpu(&self) -> u32

Returns the target CPU number for this thread.

This may be different from the CPU tasks actually run on if the affinity has not yet been set for the thread.

pub fn is_affinity_set(&self) -> bool

Returns whether this thread’s CPU affinity has been set to the intended CPU.

pub async fn wait_for_affinity(&self)

Waits for the affinity to be set to this thread’s intended CPU. If the CPU was not online when the thread was created, then this will block until the CPU is online and someone calls try_set_affinity.

pub fn set_spawn_notifier(&self, f: impl 'static + Send + FnOnce()) -> bool

Sets a function to be called when the thread gets spawned.

Return false if the thread is already spawned.
