enlace_auth.stores.prefixed

PrefixedStore — MutableMapping wrapper that scopes keys under a prefix.

The per-user injection pattern: a single base store is shared across all users and apps, but each request sees a PrefixedStore(base, f"{user_id}/{app_id}/") so keys can’t collide across tenants.

Keys the caller passes are validated via sanitize_key; the prefix itself is sanitized at construction (each slash-separated segment).

Classes

PrefixedStore(base, prefix)

Transparently prepend a prefix to every key operation on a base store.

class enlace_auth.stores.prefixed.PrefixedStore(base, prefix)

Bases: MutableMapping

Transparently prepend a prefix to every key operation on a base store.

keys_under(sub='')

Keys (without this store’s prefix) that start with sub.

Uses the base store’s own keys_under when it has one (the file backend walks only the matching directory), else filters a full iteration.

Return type:

Iterator[str]
