Implementations

impl ShadowStorage

pub fn checkpoint( repo_path: &Path, session_id: &str, files: &[FileSnapshot], removals: &[FileRemoval], meta: &ShadowMeta, ) -> Result<usize>

Create or add a checkpoint on a shadow branch.

If the shadow ref doesn’t exist yet, creates the initial checkpoint (checkpoint 0) with an empty-tree base and no parent commit. Otherwise appends an incremental checkpoint on top of the existing tip.

Returns the checkpoint number.

pub fn read_checkpoint( repo_path: &Path, session_id: &str, checkpoint: Option<usize>, ) -> Result<Vec<FileSnapshot>>

Read file snapshots from a checkpoint. None = latest.

pub fn list_checkpoints( repo_path: &Path, session_id: &str, ) -> Result<Vec<CheckpointInfo>>

List all checkpoints for a session.

pub fn read_meta( repo_path: &Path, session_id: &str, ) -> Result<Option<ShadowMeta>>

Read the shadow meta from the latest checkpoint.

pub fn condense( repo_path: &Path, session_id: &str, final_hail: &[u8], final_meta: &[u8], ) -> Result<String>

Condense: archive the final HAIL to the sessions branch, then delete the shadow.

pub fn drop(repo_path: &Path, session_id: &str) -> Result<bool>

Delete the shadow ref without archiving.

pub fn list(repo_path: &Path) -> Result<Vec<ShadowMeta>>

List all active shadow sessions.
