Struct tikv_jemalloc_ctl::opt::lg_tcache_max

pub struct lg_tcache_max;

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 tikv_jemalloc_ctl::opt;
let lg_tcache_max = opt::lg_tcache_max::read().unwrap();
println!("max cached allocation size: {}", 1 << lg_tcache_max);
