Trait Callback

pub trait Callback: Send {
    // Required method
    fn called(&self, cmd: Command, snip: Pktsnip<Shared>);
}

Available on riot_module_gnrc_netapi_callbacks only.

Callback trait for registration with netreg.

This is expressed as a trait rather than a FnMut because the callback generally needs to be statically allocated, and a closure (which can not be named) can not.

Required Methods

fn called(&self, cmd: Command, snip: Pktsnip<Shared>)

A network command to which the callback has been registered happened.

This just takes a &self because multiple threads could concurrently create network events from different devices.
