Function jemalloc_ctl::opt::lg_tcache_max

pub fn lg_tcache_max() -> Result<usize>

Returns 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

extern crate jemallocator;
extern crate jemalloc_ctl;

#[global_allocator]
static ALLOC: jemallocator::Jemalloc = jemallocator::Jemalloc;

fn main() {
    println!("max cached allocation size: {}", 1 << jemalloc_ctl::opt::lg_tcache_max().unwrap());
}
