Struct DiffPresentation 

pub struct DiffPresentation { /* private fields */ }

Eager row indexes and cheap descriptors. Syntax and frontend widgets are not constructed here.

Implementations

impl DiffPresentation

pub fn new( document: Arc<DiffDocument>, options: PresentationOptions, ) -> DiffPresentation

Indexes a document once for O(1) row lookup and slicing.

pub fn with_projection( document: Arc<DiffDocument>, options: PresentationOptions, projection: &ContentProjection, ) -> DiffPresentation

Builds a windowed projection over the document’s complete-file sources.

pub const fn document(&self) -> &Arc<DiffDocument>

Returns the retained immutable snapshot.

pub const fn layout(&self) -> Layout

pub fn row_count(&self) -> usize

Total number of rows.

pub fn row(&self, index: usize) -> Option<&PresentedRow>

Returns one row in O(1).

pub fn rows(&self, range: Range<usize>) -> &[PresentedRow]

Returns a clamped visible row slice without allocating.

pub fn file_range(&self, file_index: usize) -> Option<Range<usize>>

Returns the row range occupied by a file.

pub fn hunk_range( &self, file_index: usize, hunk_index: usize, ) -> Option<Range<usize>>

Returns the row range occupied by a hunk, including its header.

pub fn cell_anchor( &self, row: &PresentedRow, cell: &PresentedCell, ) -> Option<LineAnchor>

pub fn anchor_at(&self, row_index: usize, side: DiffSide) -> Option<LineAnchor>

pub fn source_document( &self, row: &PresentedRow, cell: &PresentedCell, ) -> Option<&SourceDocument>

Returns the immutable complete source containing cell.

pub fn source_path<'a>( &'a self, row: &PresentedRow, cell: &PresentedCell, ) -> Option<&'a str>

Returns the side-specific repository path used as a syntax language hint.

pub fn hunk_sequence<'a>( &'a self, row: &PresentedRow, cell: &PresentedCell, ) -> Option<HunkSequence<'a>>

Describes the hunk-side line sequence containing a patch cell so hosts can keep multiline syntax context when no complete source exists.

pub fn cell_context<'a>( &'a self, row: &PresentedRow, cell: &'a PresentedCell, ) -> CellContext<'a>

pub fn language_at(&self, row_index: usize) -> &str

pub fn row_path(&self, row: &PresentedRow) -> &str

Repository path of the file a row belongs to, usable as a language hint.

pub fn row_showing_anchor(&self, anchor: &LineAnchor) -> Option<usize>

Returns the presentation row displaying an anchor in O(1) after its file has been located.

pub fn source_location( &self, row: &PresentedRow, cell: &PresentedCell, ) -> Option<SourceLocation>

pub fn row_showing_source(&self, location: &SourceLocation) -> Option<usize>

pub fn gap_info(&self, row_index: usize) -> Option<&GapInfo>

pub fn row_shows_anchor(&self, row: &PresentedRow, anchor: &LineAnchor) -> bool

pub fn is_commentable(&self, index: usize) -> bool

pub fn is_navigable(&self, index: usize) -> bool

pub fn first_navigable(&self, range: Range<usize>) -> Option<usize>

pub fn last_navigable(&self, range: Range<usize>) -> Option<usize>

pub fn step_navigable( &self, from: usize, backward: bool, range: &Range<usize>, ) -> Option<usize>
