Struct LoopbackChannelName 

pub struct LoopbackChannelName<'a> { /* private fields */ }

Borrowed view of a parsed loopback channel name. No allocation.

mod_loopback names its pair loopback/<extension>-a and -b, from the destination with the /context/dialplan tail stripped and an app= form reduced to the bare application token. Some only for names carrying a leg suffix; other drivers return None.

This is the only field that answers whether a loopback leg emitted an event. The execute-time resignation copies every channel variable onto the real channel that continues the call and clones the resigning leg’s caller profile onto it, so is_loopback, loopback_leg and every Caller-* header – Caller-Channel-Name included – then describe a channel that is gone. Feed this parser HeaderLookup::channel_name(), which reads Channel-Name, and nothing else. Mechanics are in docs/loopback-bowout.md.

A name is what a channel calls itself, not proof of its driver: a SIP peer can rename a sofia channel through the X-FS-Channel-Name header, which mod_sofia records as the push_channel_name variable. So a name answers what kind of channel this is, and never carries an authorization decision.
