Struct Selection 

pub struct Selection { /* private fields */ }

Manages the current selection state for timeline editing.

A Selection tracks three orthogonal selection types:

• Ranges – time spans on the timeline ruler.
• Clips – individual clip IDs.
• Tracks – track indices.

Implementations

impl Selection

pub fn new() -> Self

Creates a new, empty Selection.

pub fn select_range(&mut self, range: SelectionRange, mode: SelectionMode)

Applies range to the time-range selection using mode.

pub fn merge_overlapping_ranges(&mut self)

Merges all overlapping or adjacent ranges in self.ranges.

pub fn selected_duration(&self) -> u64

Returns the total duration covered by all selected ranges.

pub fn ranges(&self) -> &[SelectionRange]

Returns a slice of the currently selected ranges.

pub fn select_clip(&mut self, id: u64, mode: SelectionMode)

Applies id to the clip selection using mode.

pub fn is_clip_selected(&self, id: u64) -> bool

Returns true if the clip with id is currently selected.

pub fn selected_clips(&self) -> &[u64]

Returns a slice of all currently selected clip IDs.

pub fn select_all_in_range( &mut self, clips: &[TimelineClipRef], range: SelectionRange, )

Selects all clips from clips whose time span overlaps range.

pub fn select_track(&mut self, track: u32, mode: SelectionMode)

Selects the track with the given index using mode.

pub fn is_track_selected(&self, index: u32) -> bool

Returns true if the track with index is currently selected.

pub fn selected_tracks(&self) -> &[u32]

Returns a slice of all currently selected track indices.

pub fn clear(&mut self)

Clears all selection state (ranges, clips, and tracks).

pub fn is_empty(&self) -> bool

Returns true if nothing at all is selected.

Trait Implementations

impl Clone for Selection

fn clone(&self) -> Selection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Selection

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

Formats the value using the given formatter.

impl Default for Selection

fn default() -> Selection

Returns the “default value” for a type.
