Struct Signature

pub struct Signature {
    pub signer: KeyIdentifier,
    pub timestamp: TimeStamp,
    pub content_hash: DigestIdentifier,
    pub value: SignatureIdentifier,
}

Defines the data used to generate the signature, as well as the signer’s identifier. The format, in addition to the signature, includes additional information, namely the signer’s identifier, the signature timestamp and the hash of the signed contents.

Fields

signer: KeyIdentifier

Signer identifier

timestamp: TimeStamp

Timestamp of the signature

content_hash: DigestIdentifier

Hash of the content signed

value: SignatureIdentifier

The signature itself

Implementations

impl Signature

pub fn new<T: HashId>( content: &T, keys: &KeyPair, derivator: DigestDerivator, ) -> Result<Self, SubjectError>

It allows the creation of a new signature

Arguments

• content: The content to sign
• keys: The KeyPair to use to generate the signature

pub fn new_from_pk_ed25519<T: HashId>( content: &T, private_key: String, derivator: DigestDerivator, ) -> Result<Self, SubjectError>

It allows the creation of a new signature using private key of ed25519

Arguments

• content: The content to sign
• private_key: The String to use to generate the key pair

pub fn new_from_pk_secp256k1<T: HashId>( content: &T, private_key: String, derivator: DigestDerivator, ) -> Result<Self, SubjectError>

It allows the creation of a new signature using private key of ed25519

Arguments

• content: The content to sign
• private_key: The String to use to generate the key pair

pub fn verify<T: HashId>(&self, content: &T) -> Result<(), SubjectError>

It allow verify the signature. It checks if the content and the signer are correct

Trait Implementations

impl BorshDeserialize for Signature

where KeyIdentifier: BorshDeserialize, TimeStamp: BorshDeserialize, DigestIdentifier: BorshDeserialize, SignatureIdentifier: BorshDeserialize,

fn deserialize_reader<R: Read>(reader: &mut R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for Signature

where KeyIdentifier: BorshSerialize, TimeStamp: BorshSerialize, DigestIdentifier: BorshSerialize, SignatureIdentifier: BorshSerialize,

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

fn try_to_vec(&self) -> Result<Vec<u8>, Error>

Serialize this instance into a vector of bytes.

impl Clone for Signature

fn clone(&self) -> Signature

Returns a duplicate 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<'de> Deserialize<'de> for Signature

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Signature

fn partial_cmp(&self, other: &Signature) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Signature

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Signature

impl StructuralPartialEq for Signature
