Struct jemalloc_ctl::opt::LgTcacheMax

pub struct LgTcacheMax(_);

A type providing access to the maximum size class (log base 2) to cache in the thread-specific cache (tcache).

At a minimum, all small size classes are cached, and at a maximum all large size classes are cached. The default maximum is 32 KiB (2^15).

Examples

use jemalloc_ctl::opt::LgTcacheMax;

let lg_tcache_max = LgTcacheMax::new().unwrap();

println!("max cached allocation size: {}", 1 << lg_tcache_max.get().unwrap());

Methods
