Struct DecorationSet 

pub struct DecorationSet { /* private fields */ }

The decorations attached to a buffer.

Implementations

impl DecorationSet

pub fn new() -> Self

pub fn push(&mut self, decoration: Decoration)

pub fn iter(&self) -> impl Iterator<Item = &Decoration>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn clear_syntax(&mut self)

Drop every decoration a producer is about to replace.

Per class, not all-derived-at-once: a re-parse must not wipe the find results, and a new search must not wipe the highlighting. Each producer clears its own.

pub fn clear_matches(&mut self)

pub fn clear_diagnostics(&mut self)

pub fn clear_derived(&mut self)

Drop every derived decoration, leaving pending agent hunks alone.

pub fn remove_proposal(&mut self, proposal: ProposalId)

Drop every hunk belonging to a proposal — it was accepted, rejected, or withdrawn.

pub fn map(&mut self, changes: &ChangeSet)

Carry every decoration through an applied change.

Positions map as usual, but disturbance is handled per class, and this is where ADR-0006 §4’s policy reaches the screen:

• Derived decorations (syntax, diagnostics) whose range was disturbed are dropped. Their producer recomputes them; a half-mapped highlight is worse than none, because it colours the wrong text.
• Hunks are kept and marked HunkState::Conflicted. A pending proposal must never vanish silently — the human is mid-review, and “your edit collided with this change” is information they need.

pub fn for_line( &self, line_start: usize, line_end: usize, ) -> Vec<LineDecoration>

The decorations overlapping line_start..line_end, clipped to it and rebased to offsets relative to line_start.

Sorted by start so the renderer can walk them in order. Zero-width anchors are kept — they are exactly the “text goes here” markers of HunkSide::Added.

Trait Implementations

impl Clone for DecorationSet

fn clone(&self) -> DecorationSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecorationSet

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

Formats the value using the given formatter.

impl Default for DecorationSet

fn default() -> DecorationSet

Returns the “default value” for a type.
