Struct gpiocdev_uapi::v2::LineEdgeEvent

#[repr(C)]
pub struct LineEdgeEvent {
    pub timestamp_ns: u64,
    pub kind: LineEdgeEventKind,
    pub offset: Offset,
    pub seqno: u32,

    /* private fields */
}

Information about an edge event on a requested line.

Fields

timestamp_ns: u64

The best estimate of time of event occurrence, in nanoseconds.

By default the timestamp is read from CLOCK_MONOTONIC and is intended to allow the accurate measurement of the time between events. It does not provide the wall-clock time.

If the LineFlags::EVENT_CLOCK_REALTIME flag is set then the timestamp is read from CLOCK_REALTIME.

kind: LineEdgeEventKind

The event trigger identifier.

offset: Offset

The offset of the line that triggered the event.

seqno: u32

The sequence number for this event in the sequence of events for all the lines in this line request.

line_seqno: u32

The sequence number for this event in the sequence of events on this particular line.

Implementations

impl LineEdgeEvent

pub fn from_buf(d: &[u8]) -> Result<&LineEdgeEvent>

Read an edge event from a buffer.

Trait Implementations

impl Clone for LineEdgeEvent

fn clone(&self) -> LineEdgeEvent

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LineEdgeEvent

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

Formats the value using the given formatter.

impl PartialEq<LineEdgeEvent> for LineEdgeEvent

fn eq(&self, other: &LineEdgeEvent) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
