Overview

Package types contains primitive, plain-old-data types including:

  • Cedar data types, which implement the Value interface
  • Entity and friends, including a JSON marshaler for interacting with JSON-encoded entities
  • The Pattern struct, used for both programmatic and textual/JSON AST construction
  • Authorization types used by both the cedar package and the experimental batch package, in order to avoid a circular dependency

Types contained herein which are generally useful to the public are re-exported via the cedar package; it should be unlikely that users need to import this package directly.
