Struct chain_crypto::algorithms::sumed25519::sum::Signature

pub struct Signature(Vec<u8>);

Signature using the repetitive MMM sum composition

Serialization:

• period
• sigma : ED25519 individual signature linked to period
• ED25519 public key of this period
• public keys : merkle tree path elements

Tuple Fields

0: Vec<u8>

Implementations

impl Signature

pub fn from_bytes(depth: Depth, bytes: &[u8]) -> Result<Self, Error>

Trait Implementations

impl AsRef<[u8]> for Signature

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Signature

fn clone(&self) -> Signature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Signature

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

Formats the value using the given formatter.
