Struct Hash 

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

A BLAKE3 content hash (32 bytes / 256 bits).

Used as the canonical identifier for blobs in the content-addressed store. BLAKE3 provides SIMD-accelerated hashing with a 2^128 collision resistance bound.

Tuple Fields

0: [u8; 32]

The raw 32-byte digest.

Implementations

impl Hash

pub const ZERO: Self

The zero hash (all zeros). Used as a sentinel value.

pub fn from_data(data: &[u8]) -> Self

Compute the BLAKE3 hash of arbitrary data.

pub fn from_hex(hex: &str) -> Result<Self, HashError>

Parse a hash from a 64-character lowercase hex string.

pub fn to_hex(&self) -> String

Convert to a 64-character lowercase hex string.

pub fn bucket(&self) -> u8

The 2-hex-prefix bucket index (0..=255) of this hash in the blob store layout: blobs live under objects/<2-hex-prefix>/<rest>, where the 2-hex prefix is the lowercase-hex encoding of this byte (the digest’s first byte). See BlobStore::blob_path.

This is a pure function of the digest; Kani-verified in tests/kani.rs to agree with the hex text form and to be stable under the to_hex/from_hex roundtrip.

pub fn as_blake3(&self) -> Blake3Hash

Convert to a blake3::Hash value.

Trait Implementations
