pub struct DiffEngine;

Generates and applies diffs between file versions

Implementations

impl DiffEngine

pub fn new() -> Self

Generates a unified diff between two file versions

Arguments

• old - The original file content
• new - The new file content
• path - The path of the file being diffed

Returns

A FileDiff containing hunks and statistics

pub fn generate_side_by_side_diff( &self, old: &str, new: &str, path: PathBuf, ) -> Result<FileDiff, FileError>

Generates a side-by-side diff between two file versions

Arguments

• old - The original file content
• new - The new file content
• path - The path of the file being diffed

Returns

A FileDiff containing hunks and statistics

pub fn apply_hunk( &self, source: &str, hunk: &DiffHunk, ) -> Result<String, FileError>

Applies a single hunk to source content

Arguments

• source - The source content to apply the hunk to
• hunk - The hunk to apply

Returns

The content with the hunk applied

pub fn compute_stats(&self, diff: &FileDiff) -> DiffStats

Computes statistics for a diff

Arguments

• diff - The diff to compute statistics for

Returns

Statistics about the diff (additions, deletions, files changed)
