Struct OffsetTable 

pub struct OffsetTable { /* private fields */ }

Pre-computed offset table for a particular frame rate.

Implementations

impl OffsetTable

pub fn build(rate: FrameRate) -> Self

Build the offset table for the given frame rate.

The table covers the full 24-hour range (1440 minute entries).

pub fn timecode_to_frame(&self, tc: &Timecode) -> Result<u64, TimecodeError>

Convert a timecode to its absolute frame offset using the table.

Errors

Returns TimecodeError::InvalidHours if the timecode is out of range.

pub fn frame_to_timecode(&self, frame: u64) -> Result<Timecode, TimecodeError>

Convert an absolute frame offset back to a timecode using the table.

Binary-searches the minute table then linearly computes seconds/frames.

Errors

Returns TimecodeError::InvalidFrames if the frame number exceeds the 24-hour range.

pub fn rate(&self) -> FrameRate

Get the frame rate this table was built for.

pub fn total_day_frames(&self) -> u64

Total number of frames in a full 24-hour day.

pub fn minute_offset(&self, minute: usize) -> Option<u64>

Look up the offset for a given minute index directly.

pub fn len(&self) -> usize

Number of entries in the table.

pub fn is_empty(&self) -> bool

Returns true when the table is empty (should never happen after build).

Performs copy-assignment from source.

impl Debug for OffsetTable

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