Struct GroupDigest 

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

GroupDigest_t (Spec §8.3.5.10). 16-Byte-Wert.

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 wenn der Wert dem UNKNOWN-Sentinel entspricht.

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

Berechnet den Digest aus einer Liste von GuidPrefixes. Sortiert die Eingabe vor dem Hashing — das Ergebnis ist also unabhaengig von der Iter-Reihenfolge des Callers.

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

LE-Bytes (Spec gibt keine Endianness vor — der Wert ist eine reine Byte-Sequenz aus dem Hash).

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

Roundtrip-Identitaet.

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

Decoded aus einem Slice. Truncated → Error.

Errors

UnexpectedEof wenn bytes.len() < 16.

Trait Implementations

impl Clone for GroupDigest

fn clone(&self) -> GroupDigest

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GroupDigest

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for GroupDigest

fn default() -> GroupDigest

Returns the “default value” for a type.

impl Hash for GroupDigest

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for GroupDigest

fn eq(&self, other: &GroupDigest) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
