Struct FileStore 

pub struct FileStore { /* private fields */ }

File-based storage backend.

Stores each principal’s entries in a JSONL file named <pr_b64>.jsonl within the configured base directory.

Example

use cyphr_storage::FileStore;

let store = FileStore::new("/var/data/cyphr");

Implementations

impl FileStore

pub fn new(base_dir: impl AsRef<Path>) -> Self

Create a new file store with the given base directory.

The directory will be created if it doesn’t exist.

impl FileStore

pub fn append_commit( &self, pr: &PrincipalGenesis, commit: &CommitEntry, ) -> Result<(), FileStoreError>

Append a commit bundle to the principal’s log.

Each commit is stored as a single JSON line containing:

• cozies: Array of coz entries
• commit_id: Commit ID (base64url)
• as: Auth State (base64url)
• sr: State Root (base64url)
• ps: Principal State (base64url)

pub fn get_commits( &self, pr: &PrincipalGenesis, ) -> Result<Vec<CommitEntry>, FileStoreError>

Get all commits from the principal’s log.

Parses each line as a CommitEntry with embedded state digests.
