Struct InstanceTable 

pub struct InstanceTable { /* private fields */ }

Available on crate feature alloc only.

The instances a backend currently reports, keyed by (service type, instance name), with no I/O.

Each slot holds the addresses of its latest report, so an address changed in place replaces the old one; an instance’s server, port and TXT are the latest reported, and it leaves the table with its last slot.
