Function riot_wrappers::gcoap::scope

pub fn scope<'env, F, R>(callback: F) -> R
where
    F: for<'id> FnOnce(&mut RegistrationScope<'env, 'id>) -> R,

Available on riot_module_gcoap only.

Give the caller a way of registering Gcoap handlers into the global Gcoap registry inside a callback. When the callback terminates, the registered handlers are deregistered again, theoretically allowing the registration of non-’static handlers.

As there is currently no way to unregister handlers, this function panics when the callback terminates. (Otherwise, it’d return the callback’s return value).
