Function handshake

pub fn handshake<AuthFn, T>(
    transport: T,
    service: Service,
    authenticate: AuthFn,
    extra_parameters: Vec<(String, Option<String>)>,
    progress: &mut impl Progress,
) -> Result<Outcome, Error>
where
    AuthFn: FnMut(Action) -> Result,
    T: Transport,

Available on crate features blocking-client or async-client only.

Perform a handshake with the server on the other side of transport, with authenticate being used if authentication turns out to be required. extra_parameters are the parameters (name, optional value) to add to the handshake, each time it is performed in case authentication is required. progress is used to inform about what’s currently happening.
