Converts this type into a shared reference of the (usually inferred) input type.

impl CBORDecodable for Signature

fn from_cbor(cbor: &CBOR) -> Result<Self>

Creates an instance of this type from CBOR symbolic representation.

fn from_cbor_data(cbor_data: &[u8]) -> Result<Self, Error>

where Self: Sized,

impl CBOREncodable for Signature

fn cbor(&self) -> CBOR

Returns the value in CBOR symbolic representation.

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

Returns the value in CBOR binary representation.

impl CBORTagged for Signature

Creates an instance of this type by decoding it from untagged CBOR.

fn from_tagged_cbor(cbor: &CBOR) -> Result<Self, Error>

where Self: Sized,

Creates an instance of this type by decoding it from tagged CBOR.

fn from_tagged_cbor_data(data: &[u8]) -> Result<Self, Error>

where Self: Sized,

Creates an instance of this type by decoding it from binary encoded tagged CBOR.

fn from_untagged_cbor_data(data: &[u8]) -> Result<Self, Error>

where Self: Sized,

Creates an instance of this type by decoding it from binary encoded untagged CBOR.

impl CBORTaggedEncodable for Signature

fn untagged_cbor(&self) -> CBOR

Returns the untagged CBOR encoding of this instance.

fn tagged_cbor(&self) -> CBOR

Returns the tagged CBOR encoding of this instance.

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

Returns the tagged value in CBOR binary representation.

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 Debug for Signature

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

Formats the value using the given formatter.

impl From<Signature> for CBOR

fn from(value: Signature) -> Self

Converts to this type from the input type.

where H: Hasher, Self: Sized,

impl PartialEq for Signature

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

fn try_from(cbor: &CBOR) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<CBOR> for Signature
