Expand description

A handle to control jemalloc profiling.

Implementations§

source§

impl JemallocProfCtl

source

pub fn lg_sample(&self) -> size_t

Returns the base 2 logarithm of the sample rate (average interval, in bytes, between allocation samples).

source

pub fn get_md(&self) -> JemallocProfMetadata

Returns the metadata of the profiler.

source

pub fn activated(&self) -> bool

Returns whether the profiler is active.

source

pub fn activate(&mut self) -> Result<(), Error>

Activate the profiler and if unset, set the start time to the current time.

source

pub fn deactivate(&mut self) -> Result<(), Error>

Deactivate the profiler.

source

pub fn dump(&mut self) -> Result<File>

Dump a profile into a temporary file and return it.

source

pub fn dump_pprof(&mut self) -> Result<Vec<u8>>

Dump a profile in pprof format (gzipped protobuf) and return a buffer with its contents.
