Enum Timestamp

pub enum Timestamp {
    TimestampDeltaUs(i64),
    TimestampAbsoluteUs(i64),
}

Deprecated. Use the |timestamp| and |timestamp_clock_id| fields in TracePacket instead.

Timestamp in microseconds (usually CLOCK_MONOTONIC).

Variants

TimestampDeltaUs(i64)

Delta timestamp value since the last TrackEvent or ThreadDescriptor. To calculate the absolute timestamp value, sum up all delta values of the preceding TrackEvents since the last ThreadDescriptor and add the sum to the |reference_timestamp| in ThreadDescriptor. This value should always be positive.

TimestampAbsoluteUs(i64)

Absolute value (e.g. a manually specified timestamp in the macro). This is a one-off value that does not affect delta timestamp computation in subsequent TrackEvents.

Implementations

impl Timestamp

pub fn encode<B>(&self, buf: &mut B)

where B: BufMut,

Encodes the message to a buffer.

pub fn merge<B>( field: &mut Option<Timestamp>, tag: u32, wire_type: WireType, buf: &mut B, ctx: DecodeContext, ) -> Result<(), DecodeError>

where B: Buf,

Decodes an instance of the message from a buffer, and merges it into self.

pub fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

Trait Implementations

impl Clone for Timestamp

fn clone(&self) -> Timestamp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Timestamp

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

Formats the value using the given formatter.

impl PartialEq for Timestamp

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

Tests for self and other values to be equal, and is used by ==.

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

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