Struct Port 

pub struct Port { /* private fields */ }

Available on crate feature hub only.

One attachment point on a Hub.

A port is both a sender and a receiver. It is the building block for custom transports: read frames from your connection and send them, and write every frame from recv back to it.

Implementations

impl Port

pub fn id(&self) -> u64

A process-unique identifier for this port (used for no-echo filtering and in log messages).

pub fn send(&self, frame: CanFrame)

Send a frame to every other port.

Never blocks. If no other port is attached the frame is discarded.

pub async fn recv(&mut self) -> Option<CanFrame>

Wait for the next frame from another port. Returns None if the hub is gone.

If this port fell more than CHANNEL_DEPTH frames behind, the frames it missed are skipped (and logged with the log feature) and reception continues with the oldest frame still in the ring.

pub fn try_recv(&mut self) -> Option<CanFrame>

Return a frame if one is ready, without waiting. Lag is handled exactly as in Port::recv.

Trait Implementations

impl Debug for Port

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
