Struct SyncMap 

pub struct SyncMap {
    pub sync_points: Vec<TcSyncPoint>,
}

A collection of sync points that defines a piecewise-linear mapping between source and target frame domains.

Fields

sync_points: Vec<TcSyncPoint>

Ordered list of sync points (sorted by source_frame)

Implementations

impl SyncMap

pub fn new() -> Self

Create an empty SyncMap

pub fn add_sync_point(&mut self, point: TcSyncPoint)

Add a sync point. The internal list is kept sorted by source_frame.

pub fn point_count(&self) -> usize

Return the number of sync points

pub fn source_to_target(&self, frame: i64) -> i64

Convert a source frame to a target frame using linear interpolation.

• If there are no sync points, returns source_frame unchanged.
• If source_frame is before the first sync point or after the last, the nearest endpoint’s offset is extrapolated.
• Otherwise, interpolates linearly between the bounding sync points.

pub fn target_to_source(&self, frame: i64) -> i64

Convert a target frame to a source frame using linear interpolation.

Uses the same piecewise-linear logic but operates on the target axis.

Trait Implementations

Performs copy-assignment from source.

impl Debug for SyncMap

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

impl Default for SyncMap

fn default() -> SyncMap

Returns the “default value” for a type.
