Struct Hunk 

pub struct Hunk {
    pub old_start: u32,
    pub old_lines: u32,
    pub new_start: u32,
    pub new_lines: u32,
    pub lines: Vec<DiffLine>,
}

A “hunk” is a standard Git concept: a contiguous group of changed lines within a single file, together with a few surrounding unchanged (context) lines for orientation.

When a file has changes in multiple separate regions, Git produces one hunk per region rather than one giant diff. For example, if lines 10-12 and lines 50-55 were modified, that file’s diff would contain two hunks.

The line numbers refer to positions in the old (before) and new (after) versions of the file:

• old_start / old_lines: where this hunk begins and how many lines it spans in the original file.
• new_start / new_lines: the same for the modified file.

These correspond to the @@ -old_start,old_lines +new_start,new_lines @@ header you see in unified diff output.

Fields

old_start: u32

old_lines: u32

new_start: u32

new_lines: u32

lines: Vec<DiffLine>

The individual lines in this hunk (context, additions, and deletions).
