Struct CheckpointStore 

pub struct CheckpointStore { /* private fields */ }

Workspace-wide, per-session checkpoint store.

Partitioned by session (issue #14): two OpenCode sessions sharing one bridge can both create checkpoints named snap1 without collision, and restoring from one session does not leak the other’s file set. Checkpoints are kept in memory only — a bridge crash drops all of them, which is a deliberate trade-off to keep this refactor bounded. Durable checkpoints are a possible follow-up.

Implementations

impl CheckpointStore

pub fn new() -> Self

pub fn create( &mut self, session: &str, name: &str, files: Vec<PathBuf>, backup_store: &BackupStore, ) -> Result<CheckpointInfo, AftError>

Create a checkpoint by reading the given files, scoped to session.

If files is empty, snapshots all tracked files for that session from the BackupStore (other sessions’ tracked files are not visible). Overwrites any existing checkpoint with the same name in this session.

Unreadable paths (e.g. deleted since their last edit) are skipped with a warning instead of failing the whole checkpoint. The paths and their errors are returned via CheckpointInfo::skipped so callers can surface them. A checkpoint is only rejected outright when every requested path fails — that case still returns a FileNotFound error so callers can distinguish “partial success” from “nothing snapshotted at all”.

pub fn restore( &self, session: &str, name: &str, ) -> Result<CheckpointInfo, AftError>

Restore a checkpoint by overwriting files with stored content.

pub fn restore_validated( &self, session: &str, name: &str, validated_paths: &[PathBuf], ) -> Result<CheckpointInfo, AftError>

Restore a checkpoint using a caller-validated path list.

pub fn file_paths( &self, session: &str, name: &str, ) -> Result<Vec<PathBuf>, AftError>

Return the file paths stored for a checkpoint.

pub fn delete(&mut self, session: &str, name: &str) -> bool

Delete a checkpoint from a session. Returns true when a checkpoint was removed.

pub fn list(&self, session: &str) -> Vec<CheckpointInfo>

List all checkpoints for this session with metadata.

pub fn total_count(&self) -> usize

Total checkpoint count across all sessions (for /aft-status).

pub fn cleanup(&mut self, ttl_hours: u32)

Remove checkpoints older than ttl_hours across all sessions. Empty session entries are pruned after cleanup.
