Enum PersistentStorageIdentity 

pub enum PersistentStorageIdentity {
    File(PathBuf),
    Opaque(String),
}

Stable identity of one durable database. File identities allow engine coordination to extend across independently constructed providers and OS processes; opaque identities coordinate providers inside one process.

Variants

File(PathBuf)

Opaque(String)

Implementations

impl PersistentStorageIdentity

pub fn for_database_path(path: &Path) -> StorageBackendResult<Self>

Resolve the stable file identity for a database path. The database file itself may not exist yet because backends materialize it on first write, so a missing file anchors the identity on its canonicalized parent directory instead of failing.
