@type t() :: %LetMe.Check{
  arg: term(),
  name: atom(),
  passed?: boolean() | nil,
  result: result() | nil
}

Representation of a single policy check.

• name - The function name in the configured check module.
• arg - An argument passed to the check function. If set, the function is expected to be a 3-arity function that takes the subject, object, and the arg as arguments. If set to nil, the function is expected to be a 2-arity function that only takes the subject and the object as arguments.
• result - The original return value of the check function.
• passed? - A boolean set depending on the return value of the check function.

result and passed? are only set when the policy is evaluated, i.e., when the the LetMe.Policy.authorize/4 or LetMe.Policy.authorize!/4 functions are called.

The result values true, :ok, and {:ok, term} are mapped to passed?: true. The result values false, :error, and {:error, term} are mapped to passed?: false.
