Enum dynpool::Scale

pub enum Scale {
    Shutdown,
    Active(usize),
    Mixed {
        active: usize,
        max_inactive: usize,
    },
    NoTerm {
        active: usize,
    },
}

A goal for the worker pool. This describes the scale that the pool should attempt to reach.

Variants

Shutdown

Shutdown the pool.

Active(usize)

Maintain the given number of active workers. Inactive worker threads are shutdown.

Mixed

Maintain the given number of active workers, and up to the given number of inactive workers. Any extra inactive worker threads are shutdown.

Fields of Mixed

active: usize

Number of active workers.

max_inactive: usize

Maximum number of inactive worker.

NoTerm

Maintain the given number of active workers, and an unlimited number of inactive workers. No worker threads will be terminated unless one panics.

Fields of NoTerm

active: usize

Number of active workers.

Methods

impl Scale

pub fn shutdown() -> Scale

Shutdown the pool.

pub fn active(num: usize) -> Scale

Scale to exactly the given number of workers.

pub fn mixed(active: usize, max_inactive: usize) -> Scale

Scale to the given number of active workers and no more than the given number of inactive workers.

pub fn no_term(active: usize) -> Scale

Scale to the given number of active workers without shutting down any inactive workers.

pub fn worker_count(self) -> usize

How many active workers should the pool scale to?
