Struct Link 

Source 
pub struct Link {
    pub recv: LinkReceiver,
    pub send: LinkSender,
    pub state: LinkState,
    pub stats: LinkStats,
}
Expand description

Transport-neutral byte stream between two peers.

Link is an ECS component owned by the entity that represents a local transport endpoint or a remote peer. It only stores buffered payloads and lifecycle/statistics state; concrete IO is handled by transport-specific components in crates such as lightyear_udp, lightyear_crossbeam, lightyear_webtransport, or lightyear_steam.

Incoming bytes flow: transport -> LinkReceiver -> higher-level systems. Outgoing bytes flow: higher-level systems -> LinkSender -> transport.

Fields§

§recv: LinkReceiver

Payloads received from the transport and waiting to be consumed by Lightyear systems.

§send: LinkSender

Payloads produced by Lightyear systems and waiting to be flushed by the transport.

§state: LinkState

Cached lifecycle state mirrored from Linking, Linked, or Unlinked.

§stats: LinkStats

Transport-observed statistics for this link.

Implementations§

Source

pub fn new(recv_conditioner: Option<LinkConditioner<Bytes>>) -> Link

Creates a link with empty send/receive buffers.

Source

pub fn send(&mut self, payload: Bytes)

Queues an outgoing payload for the transport layer.

This is the high-level convenience wrapper around LinkSender::push. It does not perform serialization, reliability, fragmentation, encryption, or IO; those responsibilities live in higher-level protocol crates and concrete transport crates.
