Struct tikv_jemalloc_ctl::stats::allocated

pub struct allocated;

Total number of bytes allocated by the application.

This statistic is cached, and is only refreshed when the epoch is advanced. See the [::epoch] type for more information.

This corresponds to stats.allocated in jemalloc’s API.

Examples

use tikv_jemalloc_ctl::{epoch, stats};
let e = epoch::mib().unwrap();
let allocated = stats::allocated::mib().unwrap();

let a = allocated.read().unwrap();
let _buf = vec![0; 1024 * 1024];
e.advance().unwrap();
let b = allocated.read().unwrap();
assert!(a < b);
