Struct TaskPoolThreadAssignmentPolicy

pub struct TaskPoolThreadAssignmentPolicy {
    pub min_threads: usize,
    pub max_threads: usize,
    pub percent: f32,
    pub on_thread_spawn: Option<Arc<dyn Fn() + Send + Sync + 'static>>,
    pub on_thread_destroy: Option<Arc<dyn Fn() + Send + Sync + 'static>>,
}

Defines a simple way to determine how many threads to use given the number of remaining cores and number of total cores

Fields

min_threads: usize

Force using at least this many threads

max_threads: usize

Under no circumstance use more than this many threads for this pool

percent: f32

Target using this percentage of total cores, clamped by min_threads and max_threads. It is permitted to use 1.0 to try to use all remaining threads

on_thread_spawn: Option<Arc<dyn Fn() + Send + Sync + 'static>>

Callback that is invoked once for every created thread as it starts. This configuration will be ignored under wasm platform.

on_thread_destroy: Option<Arc<dyn Fn() + Send + Sync + 'static>>

Callback that is invoked once for every created thread as it terminates This configuration will be ignored under wasm platform.
