Struct diem_sdk::crypto::multi_ed25519::MultiEd25519PublicKey

pub struct MultiEd25519PublicKey { /* private fields */ }

Vector of public keys in the multi-key Ed25519 structure along with the threshold.

Implementations

impl MultiEd25519PublicKey

pub fn new( public_keys: Vec<Ed25519PublicKey, Global>, threshold: u8 ) -> Result<MultiEd25519PublicKey, CryptoMaterialError>

Construct a new MultiEd25519PublicKey. — Rules — a) threshold cannot be zero. b) public_keys.len() should be equal to or larger than threshold. c) support up to MAX_NUM_OF_KEYS public keys.

pub fn public_keys(&self) -> &Vec<Ed25519PublicKey, Global>

Getter public_keys

pub fn threshold(&self) -> &u8

Getter threshold

pub fn to_bytes(&self) -> Vec<u8, Global>

Serialize a MultiEd25519PublicKey.

Trait Implementations

impl Debug for MultiEd25519PublicKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MultiEd25519PublicKey

fn deserialize<D>( deserializer: D ) -> Result<MultiEd25519PublicKey, <D as Deserializer<'de>>::Error>where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for MultiEd25519PublicKey

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

Formats the value using the given formatter.

impl From<&MultiEd25519PrivateKey> for MultiEd25519PublicKey

Implementing From<&PrivateKey<…>> allows to derive a public key in a more elegant fashion.

fn from(private_key: &MultiEd25519PrivateKey) -> MultiEd25519PublicKey

Converts to this type from the input type.

impl From<Ed25519PublicKey> for MultiEd25519PublicKey

Convenient method to create a MultiEd25519PublicKey from a single Ed25519PublicKey.

fn from(ed_public_key: Ed25519PublicKey) -> MultiEd25519PublicKey

Converts to this type from the input type.

impl Hash for MultiEd25519PublicKey

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

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 Length for MultiEd25519PublicKey

fn length(&self) -> usize

The serialized length of the data

impl PartialEq<MultiEd25519PublicKey> for MultiEd25519PublicKey

fn eq(&self, other: &MultiEd25519PublicKey) -> 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 PublicKey for MultiEd25519PublicKey

We deduce PublicKey from this.

type PrivateKeyMaterial = MultiEd25519PrivateKey

We require public / private types to be coupled, i.e. their associated type is each other.

impl Serialize for MultiEd25519PublicKey

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

Serialize this value into the given Serde serializer.

impl TryFrom<&[u8]> for MultiEd25519PublicKey

fn try_from(bytes: &[u8]) -> Result<MultiEd25519PublicKey, CryptoMaterialError>

Deserialize a MultiEd25519PublicKey. This method will also check for key and threshold validity, and will only deserialize keys that are safe against small subgroup attacks.

type Error = CryptoMaterialError

The type returned in the event of a conversion error.

impl ValidCryptoMaterial for MultiEd25519PublicKey

fn to_bytes(&self) -> Vec<u8, Global>

Convert the valid crypto material to bytes.

impl VerifyingKey for MultiEd25519PublicKey

We deduce VerifyingKey from pointing to the signature material we get the ability to do pubkey.validate(msg, signature)

type SigningKeyMaterial = MultiEd25519PrivateKey

The associated signing key type for this verifying key.

type SignatureMaterial = MultiEd25519Signature

The associated signature type for this verifying key.

fn verify_struct_signature<T>( &self, message: &T, signature: &Self::SignatureMaterial ) -> Result<(), Error>where T: CryptoHash + Serialize,

We provide the striaghtfoward implementation which dispatches to the signature.

fn batch_verify<T>( message: &T, keys_and_signatures: Vec<(Self, Self::SignatureMaterial), Global> ) -> Result<(), Error>where T: CryptoHash + Serialize,

We provide the implementation which dispatches to the signature.
