Struct orion::hazardous::ecc::x25519::PublicKey

pub struct PublicKey { /* private fields */ }

A type that represents a PublicKey that X25519 uses.

This type holds a field element and is used internally as the u-coordinate. As the RFC mandates, the most significant bit of the last byte is masked.

Errors:

An error will be returned if:

• slice is not 32 bytes.

Implementations

impl PublicKey

pub fn from_slice(slice: &[u8]) -> Result<Self, UnknownCryptoError>

Construct from a given byte slice.

pub fn len(&self) -> usize

Return the length of the object.

pub fn is_empty(&self) -> bool

Return true if this object does not hold any data, false otherwise.

NOTE: This method should always return false, since there shouldn’t be a way to create an empty instance of this object.

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

Convert this PublicKey to its byte-representation.

Trait Implementations

impl Clone for PublicKey

fn clone(&self) -> PublicKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PublicKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PublicKey

Available on crate feature serde only.

This type tries to deserialize as a Vec<u8> would. If it succeeds, the digest will be built using Self::from_slice.

Note that this allocates once to store the referenced bytes on the heap.

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error> where
    D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl From<[u8; 32]> for PublicKey

fn from(bytes: [u8; 32]) -> Self

Converts to this type from the input type.

impl PartialEq<&[u8]> for PublicKey

fn eq(&self, other: &&[u8]) -> 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 !=.

impl PartialEq<PublicKey> for PublicKey

fn eq(&self, other: &PublicKey) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Serialize for PublicKey

Available on crate feature serde only.

This type tries to serialize as a &[u8] would. Note that the serialized type likely does not have the same protections that Orion provides, such as constant-time operations. A good rule of thumb is to only serialize these types for storage. Don’t operate on the serialized types.

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error> where
    S: Serializer, 

Serialize this value into the given Serde serializer.

impl TryFrom<&[u8]> for PublicKey

Delegates to from_slice implementation

type Error = UnknownCryptoError

The type returned in the event of a conversion error.

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

Performs the conversion.

impl TryFrom<&PrivateKey> for PublicKey

type Error = UnknownCryptoError

The type returned in the event of a conversion error.

fn try_from(private_key: &PrivateKey) -> Result<Self, Self::Error>

Performs the conversion.
