Enum ThinClient 

pub enum ThinClient {
    Quic(ThinClient<QuicPool, QuicConnectionManager, QuicConfig>),
    Udp(ThinClient<UdpPool, UdpConnectionManager, UdpConfig>),
}

A thin wrapper over thin-client/ThinClient to ease construction of the ThinClient for code dealing both with udp and quic. For the scenario only using udp or quic, use thin-client/ThinClient directly.

Variants

Quic(ThinClient<QuicPool, QuicConnectionManager, QuicConfig>)

Udp(ThinClient<UdpPool, UdpConnectionManager, UdpConfig>)
