Struct SampleId

pub struct SampleId(/* private fields */);

A subset of the sample fields that can be recorded in non-SAMPLE records.

This will be empty by default unless sample_id_all was set when configuring the perf event counter.

Implementations

impl SampleId

pub fn from_sample(sample: &Sample<'_>) -> Self

Construct a SampleId by reading its fields out of a full sample struct.

pub fn pid(&self) -> Option<u32>

The process ID that generated this event.

pub fn tid(&self) -> Option<u32>

The thread ID that generated this event.

pub fn time(&self) -> Option<u64>

The time at which this event was recorded.

The clock used to record the time depends on how the clock was configured when setting up the counter.

pub fn id(&self) -> Option<u64>

The unique kernel-assigned ID for the leader of this counter group.

pub fn stream_id(&self) -> Option<u64>

The unique kernel-assigned ID for the counter that generated this event.

pub fn cpu(&self) -> Option<u32>

The CPU on which this event was recorded.

pub fn estimate_len<E: Endian>(config: &ParseConfig<E>) -> usize

Get the length in bytes that this struct would need to be parsed from the provided parser.
