Struct LineEvent

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

Information about a change to the state of a Line

Wraps kernel struct gpioevent_data.

Implementations

impl LineEvent

pub fn timestamp(&self) -> u64

Best estimate of event occurrence time, in nanoseconds

In most cases, the timestamp for the event is captured in an interrupt handler so it should be very accurate.

The nanosecond timestamp value should are captured using the CLOCK_MONOTONIC offsets in the kernel and should be compared against CLOCK_MONOTONIC values. Note that kernel versions prior to 5.7 used CLOCK_REALTIME offsets instead.

pub fn event_type(&self) -> EventType

Was this a rising or a falling edge?

Trait Implementations

impl Debug for LineEvent

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
