tls-api-stub
Stub implementation of tls-api. All operations return an error.
Useful when you need an implementation of type like TlsConnector,
but you do not intend to use it.
E. g.
fn connect<C : tls_api::TlsConnector>(host: &str, use_tls: bool) { ... }
So if the function is to be used without TLS, it can be called with stub implementation:
connect::<tls_api_stub::TlsConnector>("database", false);
