sourcepub fn from_seed(seed: &[u8; 32]) -> Pair
pub fn from_seed(seed: &[u8; 32]) -> Pair
Make a new key pair from raw secret seed material.
This is generated using schnorrkel’s Mini-Secret-Keys.
A MiniSecretKey is literally what Ed25519 calls a SecretKey, which is just 32 random bytes.
sourcepub fn from_seed_slice(seed: &[u8]) -> Result<Pair, SecretStringError>
pub fn from_seed_slice(seed: &[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(), from_phrase()
type Seed = [u8; 32]
type Seed = [u8; 32]
The type used to (minimally) encode the data required to securely create a new key pair. Read more
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. Read more
type DeriveError = Infallible
type DeriveError = Infallible
Error returned from the derive function.
sourcepub fn generate_with_phrase(password: Option<&str>) -> (Pair, String, [u8; 32])
pub fn generate_with_phrase(password: Option<&str>) -> (Pair, String, [u8; 32])

password: Option<&str>
) -> Result<(Pair, [u8; 32]), SecretStringError>
pub fn from_phrase(
phrase: &str,
password: Option<&str>
) -> Result<(Pair, [u8; 32]), SecretStringError>
Returns the KeyPair from the English BIP39 seed phrase, or None if it’s invalid.

pubkey: &<Pair as Pair>::Public
) -> bool where
M: AsRef<[u8]>,
pub fn verify<M>(
sig: &<Pair as Pair>::Signature,
message: M,
pubkey: &<Pair as Pair>::Public
) -> bool where
M: AsRef<[u8]>,
Verify a signature on a message. Returns true if the signature is good.
sourcepub fn verify_weak<P, M>(sig: &[u8], message: M, pubkey: P) -> bool where
P: AsRef<[u8]>,
M: AsRef<[u8]>,
pub fn verify_weak<P, M>(sig: &[u8], message: M, pubkey: P) -> bool where
P: AsRef<[u8]>,
M: AsRef<[u8]>,

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