Host-side handshake coordinator.

Implementations

impl HostHandshake

pub fn new(proposed: Vec<ProtocolId>) -> Self

Creates a new host handshake coordinator with the list of proposed protocols in priority order.

pub fn proposed(&self) -> &[ProtocolId]

Returns the list of proposed protocols.

pub fn start(&self) -> Result<(FrameType, Vec<u8>), HandshakeError>

Generates the initial negotiation request frame type and serialized payload.

Errors
