Struct gpio_cdev::LineEvent

pub struct LineEvent(_);

Information about a change to the state of a Line

Wraps kernel struct gpioevent_data.

Methods

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_REALTIME offsets in the kernel and should be compared against CLOCK_REALTIME values.

pub fn event_type(&self) -> EventType

Was this a rising or a falling edge?

Trait Implementations

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