pub struct PerfBufferBuilder<'a> { /* fields omitted */ }

Builds PerfBuffer instances.

Implementations

impl<'a> PerfBufferBuilder<'a>

pub fn new(map: &'a Map) -> Self

impl<'a> PerfBufferBuilder<'a>

pub fn sample_cb<NewCb: SampleCb>(self, cb: NewCb) -> PerfBufferBuilder<'a>

Callback to run when a sample is received.

This callback provides a raw byte slice. You may find libraries such as plain helpful.

Callback arguments are: (cpu, data).

pub fn lost_cb<NewCb: LostCb>(self, cb: NewCb) -> PerfBufferBuilder<'a>

Callback to run when a sample is received.

Callback arguments are: (cpu, lost_count).

pub fn pages(&mut self, pages: usize) -> &mut Self

The number of pages to size the ring buffer.

pub fn build(self) -> Result<PerfBuffer>
