Struct CounterData

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

The data retrieved by reading from a Counter.

Implementations

impl CounterData

pub fn count(&self) -> u64

The counter value.

The meaning of this field depends on how the counter was configured when it was built; see [‘Builder’].

pub fn time_enabled(&self) -> Option<Duration>

How long this counter was enabled by the program.

This will be present if ReadFormat::TOTAL_TIME_ENABLED was specified in read_format when the counter was built.

pub fn time_running(&self) -> Option<Duration>

How long the kernel actually ran this counter.

If time_enabled == time_running then the counter ran for the entire period it was enabled, without interruption. Otherwise, the counter shared the underlying hardware with others and you should adjust its value accordingly.

This will be present if ReadFormat::TOTAL_TIME_RUNNING was specified in read_format when the counter was built.

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

The number of lost samples of this event.

This will be present if ReadFormat::LOST was specified in read_format when the counter was built.
