Function nix_compat::nix_daemon::worker_protocol::server_handshake_client
source · pub async fn server_handshake_client<'a, RW: 'a>(
conn: &'a mut RW,
nix_version: &str,
trusted: Trust,
) -> Result<ProtocolVersion>
Expand description
Performs the initial handshake the server is sending to a connecting client.
During the handshake, the client first send a magic u64, to which the daemon needs to respond with another magic u64. Then, the daemon retrieves the client version, and discards a bunch of now obsolete data.
§Arguments
- conn: connection with the Nix client.
- nix_version: semantic version of the Nix daemon. “2.18.2” for instance.
- trusted: trust level of the Nix client.
§Return
The protocol version to use for further comms, min(client_version, our_version).
