Struct EphemeralPublicKey

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

An ephemeral public key for Sapling key agreement.

Public keys containing points of small order are not allowed.

It is denoted by epk in the specification. (This type does not represent KA^{Sapling}.Public, which allows any points, including of small order).

Trait Implementations

impl Clone for EphemeralPublicKey

fn clone(&self) -> EphemeralPublicKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EphemeralPublicKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EphemeralPublicKey

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&EphemeralPublicKey> for [u8; 32]

fn from(nk: &EphemeralPublicKey) -> [u8; 32]

Converts to this type from the input type.

impl From<EphemeralPublicKey> for [u8; 32]

fn from(nk: EphemeralPublicKey) -> [u8; 32]

Converts to this type from the input type.

impl PartialEq<[u8; 32]> for EphemeralPublicKey

fn eq(&self, other: &[u8; 32]) -> 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 PartialEq for EphemeralPublicKey

fn eq(&self, other: &EphemeralPublicKey) -> 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 Serialize for EphemeralPublicKey

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; 32]> for EphemeralPublicKey

fn try_from(bytes: [u8; 32]) -> Result<Self, Self::Error>

Read an EphemeralPublicKey from a byte array.

Returns an error if the key is non-canonical, or it is of small order.

Consensus

Check that a Output description’s cv and epk are not of small order, i.e. [h_J]cv MUST NOT be 𝒪_J and [h_J]epk MUST NOT be 𝒪_J.

type Error = &'static str

The type returned in the event of a conversion error.

impl ZcashDeserialize for EphemeralPublicKey

fn zcash_deserialize<R: Read>(reader: R) -> Result<Self, SerializationError>

Try to read self from the given reader.

impl ZcashSerialize for EphemeralPublicKey

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

Write self to the given writer using the canonical format.

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

Helper function to construct a vec to serialize the current struct into

fn zcash_serialized_size(&self) -> usize

Get the size of self by using a fake writer.
