Shared Types

This crate defines the types shared between the objectstore server, service, and client libraries. It is the common vocabulary that ensures all components agree on how metadata is represented, how scopes work, what permissions exist, and how objects expire.

Metadata

The [metadata] module defines Metadata, the per-object metadata structure carried alongside every object. It travels through the entire system: clients set it via HTTP headers, the server parses and validates it, the service passes it to backends, and backends persist it. The module also defines ExpirationPolicy for automatic object cleanup and Compression for payload encoding.

Scopes

The [scope] module defines Scope (a single key-value pair) and Scopes (an ordered collection). Scopes organize objects into hierarchical namespaces and double as the authorization boundary checked against JWT claims.

Auth

The [auth] module defines Permission, the set of operations that can be granted in a JWT token and checked by the server before each request.
