Struct ObservedTime 

pub struct ObservedTime {
    position: f64,
    duration: Option<f64>,
}

The last playback time actually observed while media was loaded.

Some backends expose position and duration as live properties of the loaded file — MPV’s time-pos and duration stop resolving the moment it unloads the file at EOF. Reading them straight through means that at exactly the moment end-of-file handling wants to know where playback got to, the answer is 0.0 / unknown: the player appears to rewind to 0:00 as it ends.

The polling thread records here, and the accessors fall back to it, so an EOF reads as the last timestamp rather than as zero.

Fields

position: f64

duration: Option<f64>

Implementations

impl ObservedTime

pub fn record(&mut self, position: f64, duration: f64)

Record a live reading. Non-positive durations are treated as unknown — that is how a backend reports “not established yet”, not a real zero.

pub fn record_position(&mut self, position: f64)

Record a position alone, e.g. straight after a seek, before the next poll.

pub fn reset(&mut self)

Forget everything — a different file is loading, and the previous one’s timestamp must not leak into it.

pub fn position_or_last(&self, live: Option<f64>) -> f64

The live reading if there is one, else the last observed value.

pub fn last_position(&self) -> f64

The last observed position, with no live reading to prefer — the case where the reporter is the only source there is (webview-rendered media, which the native backend cannot see at all).

pub fn last_duration(&self) -> Option<f64>

The last observed duration, if one was ever established.

pub fn duration_or_last(&self, live: Option<f64>) -> Option<f64>

The live reading if there is one, else the last observed value.
