Struct tikv_jemalloc_ctl::profiling::prof

pub struct prof;

Memory profiling enabled/disabled.

If enabled, profile memory allocation activity.

See the opt.prof_active option for on-the-fly activation/deactivation.

See the opt.lg_prof_sample option for probabilistic sampling control.

See the opt.prof_accum option for control of cumulative sample reporting.

See the opt.lg_prof_interval option for information on interval-triggered profile dumping, the opt.prof_gdump option for information on high-water-triggered profile dumping, and the opt.prof_final option for final profile dumping.

Profile output is compatible with the jeprof command, which is based on the pprof that is developed as part of the gperftools package. See HEAP PROFILE FORMAT for heap profile format documentation.

Examples

use tikv_jemalloc_ctl::profiling;
let prof = profiling::prof::read().unwrap();
println!("is memory profiling enabled: {}", prof);

Implementations

impl prof

pub fn mib() -> Result<prof_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

pub fn read() -> Result<bool>
