Struct Track

pub struct Track {
    pub id: u64,
    pub name: String,
    pub kind: TrackKind,
    pub muted: bool,
    pub solo: bool,
    pub height: f32,
    pub clips: Vec<Clip>,
    pub transitions: Vec<Transition>,
    pub bus: u64,
}

Fields

id: u64

name: String

kind: TrackKind

muted: bool

Audio: muted. Video: hidden (the “V” visibility toggle).

solo: bool

height: f32

UI height in points.

clips: Vec<Clip>

transitions: Vec<Transition>

bus: u64

Audio tracks: the bus every clip feeds unless the clip overrides it (0 = Main).

Implementations

impl Track

pub fn new(id: u64, kind: TrackKind, name: impl Into<String>) -> Self

pub fn sort(&mut self)

pub fn end(&self) -> f64

pub fn fits(&self, start: f64, dur: f64, ignore: &[u64]) -> bool

True if [start, start+dur) is free on this track, ignoring clips in ignore.

pub fn left_of(&self, right: &Clip) -> Option<&Clip>

The clip ending exactly where right starts (the left side of that cut).

pub fn transition_clips( &self, tr: &Transition, ) -> Option<(Option<&Clip>, Option<&Clip>)>

The (left, right) sides of a transition, if it is still valid. Edge transitions have one side missing: In blends nothing → clip (no left), Out blends clip → nothing (no right).

pub fn transition_at( &self, t: f64, ) -> Option<(&Transition, Option<&Clip>, Option<&Clip>)>

The transition playing at timeline time t (clamped window), with its clips.

pub fn prune_transitions(&mut self)

Drop transitions whose clips no longer abut (edge transitions only need their clip to exist).

Trait Implementations

impl Clone for Track

fn clone(&self) -> Track

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Track

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Track

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Track

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
