Struct futures_cpupool::Builder

pub struct Builder { /* fields omitted */ }

Thread pool configuration object

Builder starts with a number of workers equal to the number of CPUs on the host. But you can change it until you call create().

Methods

impl Builder

fn new() -> Builder

Create a builder a number of workers equal to the number of CPUs on the host.

fn pool_size(&mut self, size: usize) -> &mut Self

Set size of a future CpuPool

The size of a thread pool is the number of worker threads spawned

fn after_start<F>(&mut self, f: F) -> &mut Self where F: Fn() + Send + Sync + 'static

Execute function f right after each thread is started but before running any jobs on it

This is initially intended for bookkeeping and monitoring uses

fn before_stop<F>(&mut self, f: F) -> &mut Self where F: Fn() + Send + Sync + 'static

Execute function f before each worker thread stops

This is initially intended for bookkeeping and monitoring uses

fn create(&mut self) -> CpuPool

Create CpuPool with configured parameters
