Struct RangeDecorationCollection 

pub struct RangeDecorationCollection { /* private fields */ }

An independently managed collection of geometric range decorations.

Clones address the same collection. Dropping a handle does not clear it; use Self::clear to empty it or Self::dispose to release it permanently. Operations on a disposed collection or a dropped editor are harmless no-ops.

Implementations

impl RangeDecorationCollection

pub fn set(&self, decorations: Vec<RangeDecoration>, cx: &mut App)

Replace only this owner’s decorations, clipping ranges to UTF-8 boundaries.

pub fn append(&self, decorations: Vec<RangeDecoration>, cx: &mut App)

Append decorations, preserving their paint order.

pub fn clear(&self, cx: &mut App)

Empty this collection without invalidating its handles.

pub fn dispose(&self, cx: &mut App)

Release this collection, invalidating all of its cloned handles.

pub fn get_ranges(&self, cx: &App) -> Vec<Range<usize>>

Read tracked UTF-8 byte ranges in insertion order.
