impl InMemorySigner

pub fn from_random(account_id: AccountId, key_type: KeyType) -> InMemorySigner

Trait Implementations

impl Clone for InMemorySigner

fn clone(&self) -> InMemorySigner

Returns a copy 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<InMemorySigner, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<KeyFile> for InMemorySigner

fn from(key_file: KeyFile) -> InMemorySigner

Converts to this type from the input type.

impl PartialEq for InMemorySigner

fn eq(&self, other: &InMemorySigner) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for InMemorySigner

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Signer for InMemorySigner

fn public_key(&self) -> PublicKey

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

fn compute_vrf_with_proof(&self, data: &[u8]) -> (Value, Proof)

fn write_to_file(&self, path: &Path) -> Result<(), Error>

Used by test infrastructure, only implement if make sense for testing otherwise raise unimplemented.
