Fields

source: LineSource

content: String

prefix: char

line_number: Option<usize>

file_path: Option<String>

inline_spans: Vec<InlineSpan>

old_content: Option<String>

change_source: Option<LineSource>

in_current_bookmark: Option<bool>

Whether this line belongs to the current jj bookmark’s scope. None when bookmark boundary info is unavailable.

block_idx: Option<usize>

Index into the parent FileDiff’s blocks vec, if this line is part of a change block.

move_target: Option<String>

If this line is part of a moved block, the file path of the matching block.

Implementations

impl DiffLine

pub fn file_header(path: &str) -> Self

Create a file header line for a new or modified file.

pub fn deleted_file_header(path: &str) -> Self

Create a file header line for a deleted file.

pub fn renamed_file_header(old_path: &str, new_path: &str) -> Self

Create a file header line for a renamed file.

pub fn image_marker(path: &str) -> Self

Create an image marker line (UI layer will render actual image).

pub fn elided(count: usize) -> Self

Create an elided lines marker (shows count of hidden lines).

impl DiffLine

pub fn new( source: LineSource, content: String, prefix: char, line_number: Option<usize>, ) -> Self

pub fn display_width(&self) -> usize

Cached column width of content.

Computed once on first access (or in new) and reused. Treats tab as 4 columns; matches crate::diff::content_display_width.

pub fn with_old_content(self, old: &str) -> Self

pub fn with_change_source(self, change_source: LineSource) -> Self

pub fn is_change(&self) -> bool

pub fn is_addition(&self) -> bool

True if this line contributes an addition to the +/- totals. A modified line (Base + change_source) shows both an inline addition and an inline deletion, so it counts on both sides.

pub fn is_deletion(&self) -> bool

True if this line contributes a deletion to the +/- totals. A modified line carries its prior text in old_content; the renderer shows that as a - row, so it counts as a deletion alongside the +.

pub fn is_current_commit(&self) -> bool

True if this line belongs to jj’s current commit (@). Catches both direct current-commit lines and Base lines with inline modifications from @.

pub fn is_current_bookmark(&self) -> bool

True if this line belongs to the current jj bookmark’s scope.

pub fn ensure_inline_spans(&mut self)

pub fn with_file_path(self, path: &str) -> Self

pub fn is_image_marker(&self) -> bool

Check if this line is an image marker (for UI rendering)

Trait Implementations

impl Clone for DiffLine

fn clone(&self) -> DiffLine

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DiffLine

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

Formats the value using the given formatter.
