Struct Fingerprint 

pub struct Fingerprint(/* private fields */);

A fast, stable 64-bit fingerprint of a policy, a record or a cache entry.

It is not collision resistant and must not be used to claim that two blocks of bytes are identical; ContentDigest is SHA-256 and is what verification rests on.

Implementations

impl Fingerprint

pub fn of(bytes: &[u8]) -> Self

Fingerprints a block of bytes.

pub const fn get(self) -> u64

The raw value.
