Struct TextDiff 

pub struct TextDiff { /* private fields */ }

A line-level diff of two texts.

use rich_ext::diff::TextDiff;

let diff = TextDiff::new("a\nb\nc\n", "a\nB\nc\n");
assert_eq!(diff.stats(), (1, 1));
assert_eq!(
    diff.unified("old", "new"),
    "--- old\n+++ new\n@@ -1,3 +1,3 @@\n a\n-b\n+B\n c\n"
);

Implementations

impl TextDiff

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

Diff old against new line by line. A line’s terminator is part of it, so a missing final newline is a change.

pub fn context(self, lines: usize) -> Self

Unchanged lines shown around each change (default 3).

pub fn context_lines(&self) -> usize

The configured context.

pub fn ops(&self) -> &[Op]

The edit script over lines.

pub fn old_lines(&self) -> &[String]

The old side’s lines, terminators included.

pub fn new_lines(&self) -> &[String]

The new side’s lines, terminators included.

pub fn hunks(&self) -> Vec<Hunk>

The hunks at the configured context.

pub fn is_equal(&self) -> bool

Whether both sides are identical.

pub fn stats(&self) -> (usize, usize)

(added, removed) line counts.

pub fn unified(&self, old_name: &str, new_name: &str) -> String

The diff in diff -u format with old_name/new_name headers (no timestamps). Empty when the texts are equal, as diff prints nothing.

Trait Implementations

impl Clone for TextDiff

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextDiff

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

Formats the value using the given formatter.
