Struct tikv_jemalloc_ctl::stats::metadata

pub struct metadata;

Total number of bytes dedicated to jemalloc metadata.

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

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

Examples

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

e.advance().unwrap();
let size = metadata.read().unwrap();
println!("{} bytes of jemalloc metadata", size);

Implementations

impl metadata

pub fn mib() -> Result<metadata_mib>

Returns Management Information Base (MIB)

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

pub fn name() -> &'static Name

Key [::keys::Name].

impl metadata

pub fn read() -> Result<size_t>
