Trait Signature 

pub trait Signature: Clone + Sized {
    type PublicKey: PublicKey;

    const LENGTH: usize;

    // Required methods
    fn from_bytes(bytes: &[u8]) -> AptosResult<Self>;
    fn to_bytes(&self) -> Vec<u8> ;

    // Provided method
    fn to_hex(&self) -> String { ... }
}

A trait for signature types.

Required Associated Constants

const LENGTH: usize

The length of the signature in bytes.

Required Associated Types

type PublicKey: PublicKey

The public key type for this signature scheme.

Required Methods

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

Creates a signature from bytes.

Errors

Returns an error if the bytes have an invalid length or format.

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

Returns the signature as bytes.

Provided Methods

fn to_hex(&self) -> String

Returns the signature as a hex string with 0x prefix.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
