Variables

View Source
var RandReader = rand.Reader

RandReader is the random reader the protocol package will use to read random bytes from. This is exported for testing, and should not be used.

View Source
var UnmarshalDiscardBodyHandler = request.NamedHandler{Name: "awssdk.shared.UnmarshalDiscardBody", Fn: UnmarshalDiscardBody}

UnmarshalDiscardBodyHandler is a named request handler to empty and close a response's body

View Source
var ValidateEndpointHostHandler = request.NamedHandler{
	Name: "awssdk.protocol.ValidateEndpointHostHandler",
