Struct Time

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

Stream timing information, updated every graph cycle.

Obtained from Stream::time(). The now field holds the timestamp of the last update; compare it with pw_stream_get_nsec() to interpolate the current position.

All timing values are relative to the stream’s rate.

For a detailed description, see pw_time’s documentation.

Implementations

impl Time

pub fn as_raw(&self) -> &pw_time

pub fn now(&self) -> i64

The monotonic timestamp (in nanoseconds) of this report.

pub fn rate(&self) -> Fraction

The rate of ticks and delay, usually expressed as 1/samplerate.

pub fn ticks(&self) -> u64

Monotonically increasing stream position in ticks.

pub fn delay(&self) -> i64

Delay to device in ticks, including all filters on the path. Can be negative.

Convert to seconds using delay * rate.num / rate.denom.

pub fn queued(&self) -> u64

Total bytes queued in the stream.
