[][src]Struct jemalloc_ctl::background_thread

pub struct background_thread;

State of internal background worker threads.

When enabled, background threads are created on demand (the number of background threads will be no more than the number of CPUs or active arenas). Threads run periodically and handle purging asynchronously.

use jemalloc_ctl::background_thread;
let bg = background_thread::mib().unwrap();
let s = bg.read().unwrap();
println!("background_threads enabled: {}", s);
let p = background_thread::update(!s).unwrap();
println!("background_threads enabled: {} => {}", p, bg.read().unwrap());
assert_eq!(p, s);
background_thread::write(s).unwrap();
println!("background_threads enabled: {}", bg.read().unwrap());
assert_eq!(p, s);

Methods

impl background_thread[src]

pub fn mib() -> Result<background_thread_mib>[src]

Returns Management Information Base (MIB)

This value can be used to access the key without doing string lookup.

pub fn name() -> &'static Name[src]

impl background_thread[src]

pub fn read() -> Result<bool>[src]

Reads value using string API.

impl background_thread[src]

pub fn write(value: bool) -> Result<()>[src]

Writes value using string API.

impl background_thread[src]

pub fn update(value: bool) -> Result<bool>[src]

Updates key to value returning its old value using string API.
