Trait Implementations

impl AppKey for Pair

type UntypedGeneric = Pair

The corresponding type as a generic crypto type.

type Public = Public

The corresponding public key type in this application scheme.

type Pair = Pair

The corresponding key pair type in this application scheme.

type Signature = Signature

The corresponding signature type in this application scheme.

const ID: KeyTypeId

An identifier for this application-specific key type.

const CRYPTO_ID: CryptoTypeId

The identifier of the crypto type of this application-specific key type.

impl AppPair for Pair

type Generic = Pair

The wrapped type which is just a plain instance of Pair.

impl AsMut<Pair> for Pair

fn as_mut(&mut self) -> &mut Pair

Performs the conversion.

impl AsRef<Pair> for Pair

fn as_ref(&self) -> &Pair

Performs the conversion.

impl Clone for Pair

fn clone(&self) -> Pair

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CryptoType for Pair

type Pair = Pair

The pair key type of this crypto.

impl From<Pair> for Pair

fn from(inner: Pair) -> Self

Performs the conversion.

impl From<Pair> for Pair

fn from(outer: Pair) -> Self

Performs the conversion.

impl Pair for Pair

type Public = Public

The type which is used to encode a public key.

type Seed = <Pair as Pair>::Seed

The type used to (minimally) encode the data required to securely create a new key pair.

type Signature = Signature

The type used to represent a signature. Can be created from a key pair and a message and verified with the message and a public key.

type DeriveError = <Pair as Pair>::DeriveError

Error returned from the derive function.

fn generate_with_phrase(password: Option<&str>) -> (Self, String, Self::Seed)

Generate new secure (random) key pair and provide the recovery phrase.

fn from_phrase(
    phrase: &str,
    password: Option<&str>
) -> Result<(Self, Self::Seed), SecretStringError>

Returns the KeyPair from the English BIP39 seed phrase, or None if it's invalid.

fn derive<Iter: Iterator<Item = DeriveJunction>>(
    &self,
    path: Iter,
    seed: Option<Self::Seed>
) -> Result<(Self, Option<Self::Seed>), Self::DeriveError>

Derive a child key from a series of given junctions.

fn from_seed(seed: &Self::Seed) -> Self

Generate new key pair from the provided seed.

fn from_seed_slice(seed: &[u8]) -> Result<Self, SecretStringError>

Make a new key pair from secret seed material. The slice must be the correct size or it will return None.

fn sign(&self, msg: &[u8]) -> Self::Signature

Sign a message.

fn verify<M: AsRef<[u8]>>(
    sig: &Self::Signature,
    message: M,
    pubkey: &Self::Public
) -> bool

Verify a signature on a message. Returns true if the signature is good.

fn verify_weak<P: AsRef<[u8]>, M: AsRef<[u8]>>(
    sig: &[u8],
    message: M,
    pubkey: P
) -> bool

Verify a signature on a message. Returns true if the signature is good.

fn public(&self) -> Self::Public

Get the public key.

fn to_raw_vec(&self) -> Vec<u8>

Return a vec filled with raw data.

pub fn generate() -> (Self, Self::Seed)

Generate new secure (random) key pair.

pub fn from_string_with_seed(
    s: &str,
    password_override: Option<&str>
) -> Result<(Self, Option<Self::Seed>), SecretStringError>

Interprets the string s in order to generate a key Pair. Returns both the pair and an optional seed, in the case that the pair can be expressed as a direct derivation from a seed (some cases, such as Sr25519 derivations with path components, cannot).

pub fn from_string(
    s: &str,
    password_override: Option<&str>
) -> Result<Self, SecretStringError>

Interprets the string s in order to generate a key pair.

impl Wraps for Pair

type Inner = Pair

The inner type it is wrapping.
