Struct LspFoldRanges 

pub struct LspFoldRanges { /* private fields */ }

Store for LSP-provided fold ranges. Ranges are tracked as byte markers on the shared MarkerList, so inserting or deleting lines around (or inside) a fold re-aligns its header line number automatically — no manual shifting required. Fixes the “fold indicator lag” from issue #1571.

Implementations

impl LspFoldRanges

pub fn new() -> Self

Create an empty store.

pub fn is_empty(&self) -> bool

Returns true if no LSP fold ranges are currently tracked.

pub fn len(&self) -> usize

Number of tracked ranges.

pub fn clear(&mut self, marker_list: &mut MarkerList)

Drop every tracked range and release its markers.

pub fn set_from_lsp( &mut self, buffer: &Buffer, marker_list: &mut MarkerList, ranges: impl IntoIterator<Item = FoldingRange>, )

Replace the tracked set with fresh LSP-provided ranges (line-based).

Each range’s start/end lines are translated to byte offsets via Buffer::line_start_offset; ranges that can’t be resolved (e.g. line numbers past EOF) are silently dropped.

pub fn resolved( &self, buffer: &Buffer, marker_list: &MarkerList, ) -> Vec<FoldingRange>

Resolve to the current line-based LSP-style ranges (post-edit).

Ranges whose markers have been invalidated (e.g. the header line was deleted out from under them such that end comes before start) are filtered out.

Trait Implementations

impl Clone for LspFoldRanges

fn clone(&self) -> LspFoldRanges

impl Debug for LspFoldRanges

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

Formats the value using the given formatter.

impl Default for LspFoldRanges

fn default() -> LspFoldRanges

Returns the “default value” for a type.
