Struct gclient::ext::sp_core::ed25519::Pair

pub struct Pair { /* private fields */ }

A key pair.

Implementations

impl Pair

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

Get the seed for this key.

pub fn from_legacy_string(s: &str, password_override: Option<&str>) -> Pair

Exactly as from_string except that if no matches are found then, the the first 32 characters are taken (padded with spaces as necessary) and used as the MiniSecretKey.

Trait Implementations

impl AsMut<Pair> for Pair

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

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<Pair> for Pair

fn as_ref(&self) -> &Pair

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Pair

fn clone(&self) -> Pair

Returns a copy of the value.

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(outer: Pair) -> Pair

Converts to this type from the input type.

impl From<Pair> for Pair

fn from(inner: Pair) -> Pair

Converts to this type from the input type.

impl Pair for Pair

fn from_seed_slice(seed_slice: &[u8]) -> Result<Pair, SecretStringError>

Make a new key pair from secret seed material. The slice must be 32 bytes long or it will return None.

You should never need to use this; generate(), generate_with_phrase

fn derive<Iter>( &self, path: Iter, _seed: Option<[u8; 32]>, ) -> Result<(Pair, Option<[u8; 32]>), DeriveError>

where Iter: Iterator<Item = DeriveJunction>,

Derive a child key from a series of given junctions.

fn public( &self, ) -> CryptoBytes<sp_core::::ed25519::Public::{constant#0}, (PublicTag, Ed25519Tag)>

Get the public key.

fn sign( &self, message: &[u8], ) -> CryptoBytes<sp_core::::ed25519::Signature::{constant#0}, (SignatureTag, Ed25519Tag)>

Sign a message.

fn verify<M>( sig: &CryptoBytes<sp_core::::ed25519::Signature::{constant#0}, (SignatureTag, Ed25519Tag)>, message: M, public: &CryptoBytes<sp_core::::ed25519::Public::{constant#0}, (PublicTag, Ed25519Tag)>, ) -> bool

where M: AsRef<[u8]>,

Verify a signature on a message.

Returns true if the signature is good.

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

Return a vec filled with raw data.

type Public = CryptoBytes<sp_core::::ed25519::Public::{constant#0}, (PublicTag, Ed25519Tag)>

The type which is used to encode a public key.

type Seed = [u8; 32]

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

type Signature = CryptoBytes<sp_core::::ed25519::Signature::{constant#0}, (SignatureTag, Ed25519Tag)>

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.

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

Generate new secure (random) key pair.

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 an error if it’s invalid.

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

Generate new key pair from the provided seed.

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).

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

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