Struct ThreadPoolManager 

Source 
pub struct ThreadPoolManager { /* private fields */ }
Expand description

Shared manager for per-call Rayon thread-pool reuse.

This manager is intended for APIs that accept an optional thread count on each call. Requests with None or Some(0) use the configured global default. When that default is 0, work falls back to the ambient/global Rayon behavior. Positive thread counts reuse one cached dedicated pool for the most recently requested size.

Implementations§

Source§

impl ThreadPoolManager

Source

pub fn shared() -> &'static Self

Return the process-wide shared pool manager.

Source

pub fn set_global_thread_count(n_threads: usize)

Set the process-global default thread count used by omitted or zero-valued requests.

A value of 0 resets the default to the ambient/global Rayon behavior.

Source

pub fn global_thread_count() -> Option<usize>

Return the process-global default thread count used by omitted or zero-valued requests.

Returns None when the default is the ambient/global Rayon behavior.

Source

pub fn resolve_thread_request(requested_threads: Option<usize>) -> Option<usize>

Resolve an optional thread request against the process-global default.

None and Some(0) both use the configured global default. Positive thread counts bypass the global default and are returned directly.

Source

pub fn install<R: Send>( &self, requested_threads: Option<usize>, op: impl FnOnce() -> R + Send, ) -> LadduResult<R>

Execute work using the requested thread-count policy.

None and Some(0) both use the configured global default. Positive thread counts reuse a cached dedicated pool of that size.
