Struct OverviewRulerDecorationCollection 

#[non_exhaustive]
pub struct OverviewRulerDecorationCollection { /* private fields */ }

An independently managed collection of OverviewRulerDecoration values.

Each clone refers to the same collection. Dropping a handle does not clear it. Call Self::clear to empty it or Self::dispose to release it. Calls after disposal or after the editor is dropped do nothing.

Implementations

impl OverviewRulerDecorationCollection

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

Replace this collection’s decorations and clip ranges to UTF-8 boundaries.

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

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

Empty this collection and keep its handles usable.

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

Release this collection. Its cloned handles stop working.

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

Return tracked UTF-8 byte ranges in insertion order.
