Struct ClientHandle 

pub struct ClientHandle { /* private fields */ }

A resolved position in the table.

One request touches the same client four times — admit, choose a response mode, record what was sent, then record the true transmit time after the packet leaves. Looking the key up each time cost four hashes of the same address, which callgrind put at ~51% of what the server does per request once the recency index was fixed. A handle turns the three follow-ups into array indexing.

It is deliberately not a raw index: the generation makes a handle that outlived its client detectably stale instead of quietly wrong.

Implementations

impl ClientHandle

pub const INVALID: ClientHandle
