- http://docs.hydra13.apiary.io/#reference/warden:-access-control-for-resource-providers

Contains source files:

- handler.go: A HTTP handler capable of validating access tokens.

- warden_http.go: A Go API using HTTP to validate access tokens.

- warden_local.go: A Go API using storage managers to validate access tokens.

- warden_test.go: Functional tests all of the above.
