Struct GutterDecorationCollection 

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

An independently managed collection of GutterDecoration 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 GutterDecorationCollection

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

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

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

Add decorations to this collection in paint order.

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

Empty this collection and keep its handles usable. The gutter keeps its strip.

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

Release this collection. Its cloned handles stop working. The gutter drops its strip after the last gutter collection is released.

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

Return tracked UTF-8 byte ranges in insertion order.

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

Performs copy-assignment from source.

impl Debug for GutterDecorationCollection

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

Formats the value using the given formatter.

impl Default for GutterDecorationCollection

A handle that addresses no editor, so every operation on it does nothing. It can stand in for a collection until the editor that owns one exists.

fn default() -> Self
