Function format_stat_graph

atomic-cli/src/commands/diff/output.rs:34–56

Build hunks from a diff result with context lines. This function groups diff operations into hunks with the specified number of context lines around changes. # Arguments `diff_result` - The raw diff result `old_lines` - Lines from the old content `new_lines` - Lines from the new content `context` - Number of context lines to include # Returns A vector of `DiffHunk`s representing the changes w

(insertions: usize, deletions: usize, max_width: usize)
