Struct jemalloc_ctl::opt::junk

source ·
pub struct junk;
Expand description

jemalloc’s junk filling mode.

Requires --enable-fill to have been specified during build configuration.

If set to “alloc”, each byte of uninitialized allocated memory will be set to 0x5a. If set to “free”, each byte of deallocated memory will be set to 0x5a. If set to “true”, both allocated and deallocated memory will be initialized, and if set to “false” junk filling will be disabled. This is intended for debugging and will impact performance negatively.

The default is “false”, unless --enable-debug was specified during build configuration, in which case the default is “true”.

Examples

use jemalloc_ctl::opt;
let junk = opt::junk::read().unwrap();
println!("junk filling: {}", junk);

Implementations§

source§

impl junk

source

pub fn mib() -> Result<junk_mib>

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

source

pub fn name() -> &'static Name

source§

impl junk

source

pub fn read() -> Result<&'static str>

Reads value using string API.
