Struct FrameTimecode 

pub struct FrameTimecode {
    pub frame: u64,
    pub timestamp_ms: u64,
}

A precise media timecode expressed in both frame number and milliseconds.

Storing both avoids lossy round-trips between the two representations.

Fields

frame: u64

Zero-based frame index.

timestamp_ms: u64

Timestamp in milliseconds (derived from frame and fps).

Implementations

impl FrameTimecode

pub fn from_frame(frame: u64, fps_num: u32, fps_den: u32) -> Option<Self>

Creates a FrameTimecode from a frame number and a frame rate (num/den).

Panics-safe

Returns None if fps_den is zero.

pub fn from_ms(timestamp_ms: u64, fps_num: u32, fps_den: u32) -> Option<Self>

Creates a FrameTimecode from a millisecond timestamp, snapped to the nearest frame boundary.

Returns None if fps_den is zero.

pub fn duration_to(&self, other: &Self) -> Option<u64>

Returns the duration in milliseconds between self and other.

Returns None if other is before self.

pub fn frames_to(&self, other: &Self) -> Option<u64>

Returns the number of frames between self and other.

Returns None if other is before self.

Trait Implementations

impl Clone for FrameTimecode

fn clone(&self) -> FrameTimecode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrameTimecode

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

Formats the value using the given formatter.

impl PartialEq for FrameTimecode

fn eq(&self, other: &FrameTimecode) -> 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.
