Struct jemalloc_ctl::arenas::narenas

source · [−]

pub struct narenas;

Expand description

Current limit on the number of arenas.

Examples

use jemalloc_ctl::arenas;
println!("number of arenas: {}", arenas::narenas::read().unwrap());

let arenas_mib = arenas::narenas::mib().unwrap();
println!("number of arenas: {}", arenas_mib.read().unwrap());

Implementations

source

impl narenas

source

pub fn mib() -> Result<narenas_mib>

Returns Management Information Base (MIB)

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

source

pub fn name() -> &'static Name

Key crate::keys::Name.

source

impl narenas

source

pub fn read() -> Result<c_uint>

Reads value using string API.
