Struct SwarmHub 

pub struct SwarmHub { /* private fields */ }

Shared mailbox for one swarm run.

Implementations

impl SwarmHub

pub fn new() -> Self

pub fn ensure(&self, id: &str)

Register a participant so broadcasts reach them even before they send.

pub fn set_listener(&self, listener: Option<SwarmMessageListener>)

pub fn send(&self, from: &str, to: &str, text: &str) -> Result<(), String>

Deliver text from from to to (all broadcasts to every known inbox plus parent). A direct message to an unregistered id is refused with the known ids, so a typo is not silently queued where nobody reads.

pub fn drain(&self, id: &str) -> Vec<SwarmMessage>

Take every pending message for id. The inbox stays registered so later broadcasts still reach it.
