Struct PromptRepository 

pub struct PromptRepository { /* private fields */ }

An append-only store of prompt versions with diff, rollback, and blame support.

Implementations

impl PromptRepository

pub fn new() -> Self

Create an empty repository.

pub fn commit(&mut self, content: &str, author: &str, message: &str) -> u32

Commit new content and return the assigned version number.

pub fn checkout(&self, version: u32) -> Option<&PromptVersion>

Return a reference to the PromptVersion with the given number, if it exists.

pub fn diff(&self, from: u32, to: u32) -> Option<PromptDiff>

Compute the diff between two committed versions.

Returns None if either version does not exist.

pub fn log(&self) -> Vec<&PromptVersion>

Return all versions in chronological (ascending version number) order.

pub fn rollback(&mut self, to_version: u32) -> Option<u32>

Create a new commit whose content matches to_version, effectively reverting to that state. Returns the new version number, or None if to_version does not exist.

pub fn blame(&self, line: usize) -> Option<&PromptVersion>

Return the version that last introduced (or modified) the given 0-based line index in the current HEAD content.

Iterates versions in reverse order and returns the first version where the specified line differs from its parent. Returns None if the repository is empty or the line index is out of range.

pub fn history_for_author<'a>(&'a self, author: &str) -> Vec<&'a PromptVersion>

Return all versions committed by author, in chronological order.
