ContentHash

void_core::support::hash

Struct ContentHash

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

Expand description

SHA-256 hash of file content.

Used in shard entries, manifest entries, index entries, and diffs to track file identity and detect modifications.

Tuple Fields§

§0: [u8; 32]

Implementations§

impl ContentHash

pub const ZERO: Self

All-zero hash, used as a sentinel/default.

pub fn from_bytes(bytes: [u8; 32]) -> Self

Create from a raw 32-byte digest.

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

Access the underlying bytes.

pub fn to_hex(&self) -> String
