Trait Implementations

impl AsRef<Signature> for Signature

fn as_ref(&self) -> &Signature

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,

Creates an instance of this type from encoded CBOR binary data.

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

fn cbor_tags() -> Vec<Tag>

The CBOR tags assocated with this type. If more than one tag is present, they are considered equivalent for reading, but only the first one is used for writing.

impl CBORTaggedDecodable for Signature

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

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.

impl Hash for Signature

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.

impl TryFrom<&CBOR> for Signature

type Error = Error

The type returned in the event of a conversion error.

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

Performs the conversion.

impl TryFrom<CBOR> for Signature

type Error = Error

The type returned in the event of a conversion error.

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

Performs the conversion.

impl UREncodable for Signature

fn ur(&self) -> UR

Returns the UR representation of the object.

fn ur_string(&self) -> String

Returns the UR string representation of the object.

impl Eq for Signature

impl StructuralPartialEq for Signature
