pub struct Signature(_);

Expand description

Ed25519 signature.

Implementations

source

impl Signature

source

pub const BYTE_SIZE: usize = 64usize

Size of an encoded Ed25519 signature in bytes.

source

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

Parse an Ed25519 signature from a byte slice.

source

pub fn to_bytes(self) -> [u8 ; 64]

Return the inner byte array.

source

pub fn new(bytes: [u8 ; 64]) -> Self

👎 Deprecated since 1.3.0:

use ed25519::Signature::from_bytes instead

DEPRECATED: Create a new signature from a byte array.

Panics

This method will panic if an invalid signature is encountered.

Use Signature::from_bytes or Signature::try_from instead for a fallible conversion.
