Struct InMemorySigner 

pub struct InMemorySigner(/* private fields */);

In-memory signer.

Implementations

impl InMemorySigner

pub fn new(prng_seed: Option<u64>) -> Self

Creates a new InMemorySigner seeded with prng_seed. If prng_seed is None, an OsRng will be used.

pub fn generate_new(&mut self) -> AccountPublicKey

Generates a new key pair from Signer’s RNG. Use with care.

pub fn keys(&self) -> Vec<(AccountOwner, Vec<u8>)>

Returns the public key corresponding to the given owner.

Trait Implementations

impl Clone for InMemorySigner

fn clone(&self) -> InMemorySigner

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'de> Deserialize<'de> for InMemorySigner

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromIterator<(AccountOwner, AccountSecretKey)> for InMemorySigner

fn from_iter<T>(input: T) -> Self

where T: IntoIterator<Item = (AccountOwner, AccountSecretKey)>,

Creates a value from an iterator.

impl Serialize for InMemorySigner

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Signer for InMemorySigner

async fn sign( &self, owner: &AccountOwner, value: &CryptoHash, ) -> Result<AccountSignature, Error>

Creates a signature for the given value using the provided owner.

async fn contains_key(&self, owner: &AccountOwner) -> Result<bool, Error>

Returns whether the given owner is a known signer.

type Error = Error

The type of errors arising from operations on this Signer.
