Package mocks implements a mock APNS server, for unit tests.

NewPool creates a thread with numWorkers workers, which will wait until they are first needed to open a connection.

NewRequestProcessor will instantiate a worker pool for processing push attempts, with a total of poolSize workers, each maintaining at most one active encrypted TCP connection to APNs at a time.

CloseTimeout is the timeout for closing inactive APNs binary API (encrypted TCP) connections.

BinaryPushRequestProcessor contains the logic for V2 of the Binary Provider API.

PermanentError is returned by a worker because of an error that can't be fixed at the moment (e.g.

Pool is a fixed-size pool of workers responsible for sending payloads to APNs.

TemporaryError is returned by a worker for problems that can be fixed by retrying.

ConnManager abstracts creating TLS sockets to send push payloads to APNs.
