Struct AuthorPublicKey

pub struct AuthorPublicKey(/* private fields */);

Identifier for an Author

This is the corresponding [VerifyingKey] for an author. It is used as an identifier, and can be used to verify [Signature]s.

Implementations

impl AuthorPublicKey

pub fn verify( &self, msg: &[u8], signature: &Signature, ) -> Result<(), SignatureError>

Verify that a signature matches the msg bytes and was created with the Author that corresponds to this AuthorId.

pub fn as_bytes(&self) -> &[u8; 32]

Get the byte representation of this AuthorId.

pub fn from_bytes(bytes: &[u8; 32]) -> Result<Self, SignatureError>

Create from a slice of bytes.

Will return an error if the input bytes do not represent a valid [ed25519_dalek] curve point. Will never fail for a byte array returned from Self::as_bytes. See [VerifyingKey::from_bytes] for details.

fn from(value: &Author) -> Self

Converts to this type from the input type.

impl From<&AuthorPublicKey> for AuthorId

fn from(value: &AuthorPublicKey) -> Self

Converts to this type from the input type.

impl From<Author> for AuthorPublicKey

fn from(value: Author) -> Self

Converts to this type from the input type.

impl From<AuthorPublicKey> for AuthorId

fn from(value: AuthorPublicKey) -> Self

Converts to this type from the input type.

fn from(value: VerifyingKey) -> Self

Converts to this type from the input type.

impl FromStr for AuthorPublicKey

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for AuthorPublicKey

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,

impl Ord for AuthorPublicKey

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for AuthorPublicKey

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

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.

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<AuthorId> for AuthorPublicKey

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: AuthorId) -> Result<Self, Self::Error>

Performs the conversion.
