pub struct PerfBufferBuilder<'a, 'b> { /* private fields */ }

Builds PerfBuffer instances.

Implementations

impl<'a> PerfBufferBuilder<'a, '_>

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

Create a new PerfBufferBuilder using the provided Map.

impl<'a, 'b> PerfBufferBuilder<'a, 'b>

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

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 + 'b>(self, cb: NewCb) -> PerfBufferBuilder<'a, 'b>

Callback to run when a sample is received.

Callback arguments are: (cpu, lost_count).

pub fn pages(self, pages: usize) -> PerfBufferBuilder<'a, 'b>

The number of pages to size the ring buffer.

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

Build the PerfBuffer object as configured.
