pub struct Unhasher {
value: u64,
}
Expand description
This no-op hasher expects only a single write_u64
call. It’s intended for
map keys that already have hash-like quality, like Fingerprint
.

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
