Struct Digest 

pub struct Digest(pub [u8; 32]);

A BLAKE3 hash of some part of a container.

BLAKE3 rather than SHA-256 because this gets computed over whole datasets on the write path and over whole sections on any read that verifies, and the difference is large enough to change whether verification is on by default.

Tuple Fields

0: [u8; 32]

Implementations

impl Digest

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

The digest of some bytes.

pub const fn as_bytes(&self) -> &[u8; 32]

The raw bytes.

pub fn short(&self) -> String

The first sixteen hex characters, which is what belongs in a log line.

Never use this to decide whether two things are the same. It is here because a full digest in an error message is noise a reader skips, and a short one is something they read.
