Available on crate feature rpc only.

An Ethereum Signer used via RPC.

Required Methods

fn accounts(&self) -> Vec<Address>

Returns the available accounts for this signer.

fn sign<'life0, 'life1, 'async_trait>( &'life0 self, address: Address, message: &'life1 [u8], ) -> Pin<Box<dyn Future<Output = Result<Signature, SignError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Returns the signature

fn sign_transaction<'life0, 'life1, 'async_trait>( &'life0 self, request: TxReq, address: &'life1 Address, ) -> Pin<Box<dyn Future<Output = Result<T, SignError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

signs a transaction request using the given account in request

fn sign_typed_data( &self, address: Address, payload: &TypedData, ) -> Result<Signature, SignError>

Encodes and signs the typed data according EIP-712. Payload must implement Eip712 trait.

Provided Methods

fn is_signer_for(&self, addr: &Address) -> bool

Returns true whether this signer can sign for this address

fn nonce_lock(&self) -> Option<Arc<Mutex<()>>>

Returns the lock eth_sendTransaction holds for this signer’s accounts from filling the nonce until the signed transaction is in the pool, so concurrent requests from one account get distinct nonces.

None leaves those requests unserialized.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
