Struct GroupDigest 

pub struct GroupDigest(pub [u8; 16]);

GroupDigest_t (Spec §8.3.5.10). 16-byte value.

Tuple Fields

0: [u8; 16]

Implementations

impl GroupDigest

pub const WIRE_SIZE: usize = 16

Wire size: 16 bytes.

pub const UNKNOWN: Self

GROUPDIGEST_UNKNOWN (Spec): 16 null bytes.

pub fn is_unknown(self) -> bool

true if the value equals the UNKNOWN sentinel.

pub fn from_prefixes(prefixes: &[GuidPrefix]) -> Self

Computes the digest from a list of GuidPrefixes. Sorts the input before hashing — the result is thus independent of the caller’s iteration order.

pub fn to_bytes(self) -> [u8; 16]

LE bytes (the spec specifies no endianness — the value is a pure byte sequence from the hash).

pub fn from_bytes(bytes: [u8; 16]) -> Self

Roundtrip identity.

pub fn read_from(bytes: &[u8]) -> Result<Self, WireError>

Decodes from a slice. Truncated → error.

Errors

UnexpectedEof if bytes.len() < 16.
