Struct GatewayChannel 

pub struct GatewayChannel {
    pub channel: Channel,
    pub nodename: Option<String>,
    pub topology: Option<Vec<u8>>,
}

High level logic for gateways (mirrors Gateway.GatewayChannel).

This is the TARGET side of a tree channel: it receives the configuration from the admin node, ACKs it, and then accepts control messages. Any processing failure — including undecodable payloads such as a gateway message stamped with an unsupported pickle protocol — is turned into an Error reply sent back to the initiator, after which the channel is closed (fatal channel error).

Fields

channel: Channel

The underlying communication channel (target end: initiator=false).

nodename: Option<String>

This gateway’s node name (from CFG or system hostname fallback).

topology: Option<Vec<u8>>

Decoded topology payload received in CFG.

Implementations

impl GatewayChannel

pub fn new() -> Self

Create a new gateway channel ready to accept communication.

pub fn close(&mut self)

Close the gateway channel (mirrors GatewayChannel.close).

pub fn feed(&mut self, data: &str)

Feed raw incoming data to the channel, mirroring the read side of upstream Channel.ev_read for a target: parse errors are reported back to the initiator as an Error message and close the channel.

pub fn recv(&mut self, msg: Message)

Handle one incoming message (mirrors GatewayChannel.recv).

Dispatch errors are reported back to the initiator as an Error message, then the channel is closed — including configuration payload decode failures (90d3195’s gateway side: the admin later reports this reason as gateway stderr).

Trait Implementations

impl Debug for GatewayChannel

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

Formats the value using the given formatter.

impl Default for GatewayChannel

fn default() -> Self

Returns the “default value” for a type.
