# Bombay Address

Bombay Address maps application-defined address values to typed endpoints. A
successful claim returns a `Lease`; that lease exclusively owns one registration
generation and releases it on drop.

```rust
use bombay_address::AddressSpace;

let routes = AddressSpace::new();
let lease = routes.claim("jobs/thumbnail", "mailbox-1")?;
assert_eq!(routes.resolve(&"jobs/thumbnail"), Some("mailbox-1"));
drop(lease);
# Ok::<(), bombay_address::AddressInUse<&str>>(())
```

Use it when a runtime needs local address ownership without a registry,
discovery protocol, messaging framework, or erased endpoint type.
