Struct ChangeHistory 

pub struct ChangeHistory { /* private fields */ }

Aggregated change history for a codebase.

Stores changes indexed by file path and commit for efficient lookup. Does not require git integration at runtime; data can be pre-populated from any source (git, manual, tests).

Implementations

impl ChangeHistory

pub fn new() -> Self

Create a new empty change history.

pub fn add_change(&mut self, change: FileChange)

Add a change to the history.

The change is indexed by its path and commit ID, and appended to the chronological list.

pub fn changes_for_path(&self, path: &Path) -> &[FileChange]

Get all changes for a given file path.

pub fn files_in_commit(&self, commit_id: &str) -> &[FileChange]

Get all files changed in a given commit.

pub fn change_count(&self, path: &Path) -> usize

Get the total number of changes recorded for a path.

pub fn bugfix_count(&self, path: &Path) -> usize

Get the number of bugfix changes for a path.

pub fn all_commits(&self) -> Vec<&str>

Get all unique commit IDs.

pub fn chronological(&self) -> &[FileChange]

Get all changes in chronological order.

pub fn all_paths(&self) -> Vec<&Path>

Get all tracked file paths.

pub fn authors_for_path(&self, path: &Path) -> Vec<String>

Get unique authors for a path.

pub fn total_churn(&self, path: &Path) -> u64

Get total churn (lines added + deleted) for a path.

pub fn total_changes(&self) -> usize

Get the total number of changes across all files.

pub fn total_commits(&self) -> usize

Get the total number of unique commits.

pub fn latest_timestamp(&self, path: &Path) -> u64

Get the most recent change timestamp for a path, or 0 if none.

pub fn oldest_timestamp(&self, path: &Path) -> u64

Get the oldest change timestamp for a path, or 0 if none.

Trait Implementations

impl Clone for ChangeHistory

fn clone(&self) -> ChangeHistory

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChangeHistory

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

Formats the value using the given formatter.

impl Default for ChangeHistory

fn default() -> ChangeHistory

Returns the “default value” for a type.
