Struct Bisect 

pub struct Bisect;

Bisect operations — start, good, bad, skip, reset, and reading the state of a bisect already in progress.

Uses the git CLI. Every mutating call is a local operation; none touches the network.

Implementations

impl Bisect

pub fn in_progress(repo: &Repository) -> bool

Whether a bisect is currently running.

A file-existence check, deliberately: this is called from the transient builder on the actor thread to decide which rows to show, and spawning git there to answer a yes/no question would be process-spawn latency on a keystroke path. .git/BISECT_LOG is what git itself creates on bisect start and removes on bisect reset.

pub fn state(repo: &Repository) -> Result<Option<BisectState>>

The state of the bisect in progress, or None if none is.

pub fn start( repo: &Repository, bad: Option<&str>, good: Option<&str>, ) -> Result<BisectStep>

Start a bisect.

bad and good are optional: git bisect start with neither begins an unbounded bisect the user then narrows with good / bad, which is git’s own behaviour and worth preserving.

pub fn good(repo: &Repository, rev: Option<&str>) -> Result<BisectStep>

Mark a revision good (None = the one checked out).

pub fn bad(repo: &Repository, rev: Option<&str>) -> Result<BisectStep>

Mark a revision bad (None = the one checked out).

pub fn skip(repo: &Repository, rev: Option<&str>) -> Result<BisectStep>

Skip a revision that cannot be tested (None = the one checked out).

pub fn reset(repo: &Repository) -> Result<()>

End the bisect and return to the ref it started from.

pub fn log(repo: &Repository) -> Result<String>

The bisect log — every mark made so far, in git’s replayable format.
