Struct ThreadpoolBuilder

pub struct ThreadpoolBuilder { /* private fields */ }

A builder for AffinitizedThreadpool.

Implementations

impl ThreadpoolBuilder

pub fn new() -> Self

Returns a new builder.

pub fn max_bounded_workers(&mut self, n: u32) -> &mut Self

Sets the maximum number of bounded kernel workers for each worker ring, per NUMA node.

This defaults in the kernel to min(io_ring_size, cpu_count * 4).

pub fn max_unbounded_workers(&mut self, n: u32) -> &mut Self

Sets the maximum number of unbounded kernel workers for each worker ring, per NUMA node.

This defaults to the process’s RLIMIT_NPROC limit at time of threadpool creation.

pub fn ring_size(&mut self, ring_size: u32) -> &mut Self

Sets the IO ring size. Defaults to 256.

pub fn build(&self) -> Result<AffinitizedThreadpool>

Builds the thread pool.

Trait Implementations

impl Clone for ThreadpoolBuilder

fn clone(&self) -> ThreadpoolBuilder

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ThreadpoolBuilder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
