Struct NoSignature

pub struct NoSignature;

A zero-sized type representing an empty signature. This type is used when no actual signature is needed, but the type system requires a signature type. It implements SignatureEncoding with an empty byte array representation.

Trait Implementations

impl Clone for NoSignature

fn clone(&self) -> NoSignature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl SignatureEncoding for NoSignature

type Repr = [u8; 0]

Byte representation of a signature.

fn to_bytes(&self) -> Self::Repr

Encode signature as its byte representation.

fn encoded_len(&self) -> usize

Get the length of this signature when encoded.

impl Signer<NoSignature> for NoSigningKey

fn try_sign(&self, _msg: &[u8]) -> Result<NoSignature, Error>

Attempts to sign a message, always returning NoSignature.

Arguments

• _msg - The message to sign (ignored)

Returns

• Ok(NoSignature) - Always succeeds

fn sign(&self, msg: &[u8]) -> S

Sign the given message and return a digital signature

impl<'a> TryFrom<&'a [u8]> for NoSignature

fn try_from(value: &'a [u8]) -> Result<Self, Self::Error>

Attempts to create a NoSignature from a byte slice.

Arguments

• value - The byte slice to convert

Returns

• Ok(NoSignature) if the slice is empty
• Err(()) if the slice contains any bytes

type Error = ()

The type returned in the event of a conversion error.

impl TryInto<[u8; 0]> for NoSignature

fn try_into(self) -> Result<[u8; 0], Self::Error>

Converts a NoSignature into an empty byte array.

Returns

• Ok([0; 0]) - An empty byte array

type Error = ()

The type returned in the event of a conversion error.

impl Verifier<NoSignature> for NoVerifyingKey

fn verify(&self, _: &[u8], _: &NoSignature) -> Result<(), Error>

Verifies a signature, always succeeding.

Arguments

• _ - The message (ignored)
• _ - The signature (ignored)

Returns

• Ok(()) - Always succeeds
