Trait Implementations

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 Encode for Signature

fn encode<E>(&self, encoding: &E) -> Vec<u8> where
    E: Encoding, 

Encode an Ed25519 signature with the given encoding (e.g. hex, Base64)

fn encode_to_string<E>(&self, encoding: &E) -> Result<String, Error> where
    E: Encoding, 

Encode self to a String using the provided Encoding, returning the encoded value or a Error.

fn encode_to_writer<W, E>(
    &self,
    writer: &mut W,
    encoding: &E
) -> Result<usize, Error> where
    E: Encoding,
    W: Write, 

Encode self with the given Encoding, writing the result to the supplied io::Write type, returning the number of bytes written or a Error.

fn encode_to_file<P, E>(&self, path: P, encoding: &E) -> Result<File, Error> where
    E: Encoding,
    P: AsRef<Path>, 

Encode self and write it to a file at the given path, returning the resulting File or a Error.

impl Eq for Signature

impl Debug for Signature

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

Formats the value using the given formatter.

impl Signature for Signature

fn from_bytes<B>(bytes: B) -> Result<Signature, Error> where
    B: AsRef<[u8]>, 

Create an Ed25519 signature from its serialized byte representation

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

Borrow this signature as serialized bytes

fn into_vec(self) -> Vec<u8>

impl PartialEq<Signature> for Signature

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

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

#[must_use]

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