source · pub struct Pair { /* private fields */ }
Expand description
A key pair.
Implementations§
source§impl Pair
impl Pair
sourcepub fn from_legacy_string(s: &str, password_override: Option<&str>) -> Pair
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.
sourcepub fn sign_prehashed(&self, message: &[u8; 32]) -> Signature
pub fn sign_prehashed(&self, message: &[u8; 32]) -> Signature
Sign a pre-hashed message

impl Pair for Pair
source§fn from_seed_slice(seed_slice: &[u8]) -> Result<Pair, SecretStringError>
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
source§fn derive<Iter>(
&self,
path: Iter,
_seed: Option<[u8; 32]>
) -> Result<(Pair, Option<[u8; 32]>), DeriveError>where
Iter: Iterator<Item = DeriveJunction>,
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.
source§fn verify<M>(sig: &Signature, message: M, public: &Public) -> boolwhere
M: AsRef<[u8]>,
fn verify<M>(sig: &Signature, message: M, public: &Public) -> boolwhere M: AsRef<[u8]>,
Verify a signature on a message. Returns true if the signature is good.
§type Seed = [u8; 32]
type Seed = [u8; 32]
The type used to (minimally) encode the data required to securely create
a new key pair.
§type Signature = Signature
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.
source§fn generate_with_phrase(password: Option<&str>) -> (Self, String, Self::Seed)
fn generate_with_phrase(password: Option<&str>) -> (Self, String, Self::Seed)
Generate new secure (random) key pair and provide the recovery phrase. Read more
source§fn from_phrase(
phrase: &str,
password: Option<&str>
) -> Result<(Self, Self::Seed), SecretStringError>
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.source§fn from_seed(seed: &Self::Seed) -> Self
fn from_seed(seed: &Self::Seed) -> Self
Generate new key pair from the provided
seed
. Read moresource§fn from_string_with_seed(
s: &str,
password_override: Option<&str>
) -> Result<(Self, Option<Self::Seed>), SecretStringError>
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). Read moresource§fn from_string(
s: &str,
password_override: Option<&str>
) -> Result<Self, SecretStringError>
fn from_string( s: &str, password_override: Option<&str> ) -> Result<Self, SecretStringError>
Interprets the string
s
in order to generate a key pair. Read moreAuto Trait Implementations§
