Struct Timestamp 

pub struct Timestamp {
    pub time_us: i64,
    pub pts: Option<i64>,
    pub time_base: Option<(i32, i32)>,
}

A detection event timestamp, normalised to microseconds.

Metadata-derived events (black, silence, scd) carry only a seconds string, so pts/time_base are None. Per-frame measurement events (r128, cropdetect) are stamped from the raw frame pts + time_base, so both are populated.

Fields

time_us: i64

Authoritative time in microseconds.

pts: Option<i64>

Raw presentation timestamp, when the event came from a frame pts.

time_base: Option<(i32, i32)>

Raw (num, den) time base, when the event came from a frame pts.

Implementations

impl Timestamp

pub fn from_secs(s: f64) -> Option<Self>

Builds a timestamp from a seconds value (e.g. a lavfi.black_start string parsed to f64).

Returns None for non-finite input (NaN/±inf); finite values are rounded to the nearest microsecond rather than truncated.

pub fn from_pts(pts: i64, time_base: (i32, i32)) -> Self

Builds a timestamp from a raw frame pts and time_base, converting to microseconds with av_rescale_q for full precision. The caller must ensure pts is valid (not AV_NOPTS_VALUE) and time_base.1 != 0.

pub fn as_secs_f64(&self) -> f64

The timestamp as fractional seconds.

Trait Implementations

impl Clone for Timestamp

fn clone(&self) -> Timestamp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Timestamp

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.
