Struct futures_cpupool::Builder
[−]
[src]
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[src]
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
