Struct massa_signature::signature_impl::SignatureV0

pub struct SignatureV0(Signature);

Signature generated from a message and a KeyPair.

Tuple Fields

0: Signature

Implementations

impl SignatureV0

pub const SIGNATURE_SIZE_BYTES: usize = 64usize

Size of a signature

impl SignatureV0

pub fn to_bs58_check(self) -> String

Serialize a Signature using bs58 encoding with checksum.

Example

let keypair = KeyPair::generate(0).unwrap();
let data = Hash::compute_from("Hello World!".as_bytes());
let signature = keypair.sign(&data).unwrap();

let serialized: String = signature.to_bs58_check();

pub fn get_ser_len(&self) -> usize

Return the total length after serialization

pub fn to_bytes(self) -> Vec<u8>

Serialize a Signature into bytes.

Example

let keypair = KeyPair::generate(0).unwrap();
let data = Hash::compute_from("Hello World!".as_bytes());
let signature = keypair.sign(&data).unwrap();

let serialized = signature.to_bytes();

pub fn from_bytes(data: &[u8]) -> Result<SignatureV0, MassaSignatureError>

Deserialize a Signature from bytes.

IMPORTANT: providing more bytes than needed does not result in an error.

Example

let keypair = KeyPair::generate(0).unwrap();
let data = Hash::compute_from("Hello World!".as_bytes());
let signature = keypair.sign(&data).unwrap();

let serialized = signature.to_bytes();
let deserialized: Signature = Signature::from_bytes(&serialized).unwrap();

pub fn from_bs58_check(data: &str) -> Result<SignatureV0, MassaSignatureError>

Deserialize a Signature using bs58 encoding with checksum.

Example

let keypair = KeyPair::generate(0).unwrap();
let data = Hash::compute_from("Hello World!".as_bytes());
let signature = keypair.sign(&data).unwrap();

let serialized: String = signature.to_bs58_check();
let deserialized: Signature = Signature::from_bs58_check(&serialized).unwrap();

Trait Implementations

impl Clone for SignatureV0

fn clone(&self) -> SignatureV0

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SignatureV0

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

Formats the value using the given formatter.

impl Display for SignatureV0

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

Formats the value using the given formatter.

impl PartialEq for SignatureV0

fn eq(&self, other: &SignatureV0) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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