Struct TcCalculator 

pub struct TcCalculator { /* private fields */ }

Performs timecode arithmetic with drop-frame awareness.

Example

use oximedia_timecode::{Timecode, FrameRate};
use oximedia_timecode::tc_calculator::{TcCalculator, TcOperation};

let calc = TcCalculator::new(FrameRate::Fps25);
let tc = Timecode::new(0, 0, 0, 0, FrameRate::Fps25)?;
let result = calc.apply(&tc, TcOperation::AddFrames(50))?;
assert_eq!(result.timecode.seconds, 2);

Implementations

impl TcCalculator

pub fn new(frame_rate: FrameRate) -> Self

Create a new calculator for the given frame rate.

pub fn frames_per_day(&self) -> u64

Total number of frames in a 24-hour day for this frame rate.

pub fn apply( &self, tc: &Timecode, op: TcOperation, ) -> Result<TcResult, TimecodeError>

Apply an operation to a timecode.

pub fn difference(&self, a: &Timecode, b: &Timecode) -> i64

Compute the signed frame difference b - a. Positive means b is later; negative means b is earlier (wrap is ignored).

pub fn max_tc<'a>(&self, a: &'a Timecode, b: &'a Timecode) -> &'a Timecode

Return the later of two timecodes.

pub fn min_tc<'a>(&self, a: &'a Timecode, b: &'a Timecode) -> &'a Timecode

Return the earlier of two timecodes.

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

Performs copy-assignment from source.

impl Debug for TcCalculator

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