Trait JemallocProfCtlExt 

pub trait JemallocProfCtlExt {
    // Required methods
    fn dump_stats(&mut self, json_format: bool) -> Result<String>;
    fn stats(&self) -> Result<JemallocStats>;
    fn pause(&self) -> Result<()>;
    fn resume(&self) -> Result<()>;
}

Required Methods

fn dump_stats(&mut self, json_format: bool) -> Result<String>

fn stats(&self) -> Result<JemallocStats>

fn pause(&self) -> Result<()>

Pauses allocation sampling by clearing jemalloc’s prof.active mallctl.

Unlike JemallocProfCtl::deactivate, this leaves prof.reset untouched, so the profile accumulated so far and the profiling metadata (start time, sample rate) survive. Pair with resume to keep extending the same profile. Use this to briefly stop sampling, for example while capturing a CPU profile, without discarding the heap profile collected so far. A caller that intends to start a fresh profile wants JemallocProfCtl::deactivate instead.

Takes &self deliberately: pausing does not touch the tracked metadata, only the global mallctl.

fn resume(&self) -> Result<()>

Resumes allocation sampling by setting jemalloc’s prof.active mallctl.

The counterpart to pause. Sampling continues into the profile that pause preserved.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
