Casbin-RS is the Rust implementation of Apache Casbin, an authorization library that enforces access control based on configurable models such as ACL, RBAC, and ABAC. Policies are defined in PERM metamodel configuration files and can be persisted via adapters to files or databases like MySQL, PostgreSQL, and MongoDB.

Use cases

• enforce role-based access control in a Rust web service
• implement ACL permissions for API endpoints
• add attribute-based access control (ABAC) to an application
• store authorization policies in a database
• manage role hierarchies and user-role mappings
• switch authorization models without rewriting code

When to choose

• you need flexible, model-driven authorization in a Rust project
• you want consistent authorization logic across multiple languages via the Casbin ecosystem
• you need RBAC with role hierarchies, domains, or ABAC conditions
• you want policies persisted in files or various SQL/NoSQL databases

When to avoid

• you need a full identity provider with authentication, SSO, or user management
• your authorization needs are trivial and a simple hardcoded check suffices
• you require fine-grained ReBAC-style relationship graphs like a dedicated Zanzibar system
