Struct tikv_jemalloc_ctl::profiling::prof_final

pub struct prof_final;

Use an atexit(3) function to dump final memory usage to a file named according to the pattern <prefix>.<pid>.<seq>.f.heap, where <prefix> is controlled by the opt.prof_prefix and prof.prefix options.

Note that atexit() may allocate memory during application initialization and then deadlock internally when jemalloc in turn calls atexit(), so this option is not universally usable (though the application can register its own atexit() function with equivalent functionality).

This option is disabled by default.

Examples

use tikv_jemalloc_ctl::profiling;
let prof_final = profiling::prof_final::read().unwrap();
println!("dump final memory usage to file: {}", prof_final);

Implementations

impl prof_final

pub fn mib() -> Result<prof_final_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 crate::keys::Name.

impl prof_final

pub fn read() -> Result<bool>

Reads value using string API.
