Core types and interfaces of the Cedar policy language in Dart.
Cedar is a policy language for defining and enforcing access control policies in a declarative way. It is used in Celest for ensuring that only authorized users meeting certain criteria can access your backend.
The actual implementation of the Cedar engine is in cedar_ffi, which uses FFI and Dart's native assets feature to bind to the Rust implementation of Cedar. This package only holds the Dart AST representation and is separate from package:cedar_ffi so that the types can be used without bundling the native assets of package:cedar_ffi.
