Struct MessageRouter 

pub struct MessageRouter { /* private fields */ }

Routes messages between registered channels.

Each channel has an inbox; send enqueues a message iff the sender presents a capability authorizing a write to that channel.

Implementations

impl MessageRouter

pub fn new(issuer: SharedIssuer) -> Self

Creates an empty router gated by issuer — capabilities presented to send/receive are checked for live revocation against it, not just their structural (resource, right) shape.

pub fn register_channel(&mut self, channel: u64)

Registers a channel with an empty inbox.

pub fn send( &mut self, cap: &Capability, message: Message, ) -> Result<(), IpcError>

Sends message if cap authorizes writing message.channel.

pub fn receive( &mut self, cap: &Capability, channel: u64, ) -> Result<Vec<Message>, IpcError>

Receives (drains) all messages for channel if cap authorizes reading it.
