Server trait implementation for the HardhatApi RPC API.

Required Methods

fn hardhat_drop_transaction( &self, tx_hash: B256, ) -> impl Future<Output = RpcResult<bool>> + Send

Removes the given transaction from the mempool, if it exists.

Returns true if successful, otherwise false.

fn hardhat_impersonate_account( &self, address: Address, ) -> impl Future<Output = RpcResult<()>> + Send

Allows Hardhat Network to sign transactions as the given address.

fn hardhat_get_automine(&self) -> impl Future<Output = RpcResult<bool>> + Send

Returns true if automatic mining is enabled, and false otherwise.

fn hardhat_metadata(&self) -> impl Future<Output = RpcResult<Metadata>> + Send

Returns an object with metadata about the instance of the Hardhat network.

fn hardhat_mine( &self, blocks: Option<U256>, interval: Option<U256>, ) -> impl Future<Output = RpcResult<()>> + Send

Mines a specified number of blocks at a given interval.

fn hardhat_reset( &self, fork: Option<Forking>, ) -> impl Future<Output = RpcResult<()>> + Send

Resets back to a fresh forked state, fork from another block number or disable forking.

fn hardhat_set_balance( &self, address: Address, balance: U256, ) -> impl Future<Output = RpcResult<()>> + Send

Sets the balance for the given address.

fn hardhat_set_code( &self, address: Address, code: Bytes, ) -> impl Future<Output = RpcResult<()>> + Send

Modifies the bytecode stored at an account’s address.

fn hardhat_set_coinbase( &self, address: Address, ) -> impl Future<Output = RpcResult<()>> + Send

Sets the coinbase address to be used in new blocks.

fn hardhat_set_logging_enabled( &self, enabled: bool, ) -> impl Future<Output = RpcResult<()>> + Send

Enables or disables logging.

fn hardhat_set_min_gas_price( &self, gas_price: U256, ) -> impl Future<Output = RpcResult<()>> + Send

Changes the minimum gas price accepted by the network (in wei).

fn hardhat_set_next_block_base_fee_per_gas( &self, base_fee_per_gas: U256, ) -> impl Future<Output = RpcResult<()>> + Send

Sets the base fee of the next block.

fn hardhat_set_prev_randao( &self, prev_randao: B256, ) -> impl Future<Output = RpcResult<()>> + Send

Sets the PREVRANDAO value of the next block.

fn hardhat_set_nonce( &self, address: Address, nonce: U256, ) -> impl Future<Output = RpcResult<()>> + Send

Modifies an account’s nonce by overwriting it.

fn hardhat_set_storage_at( &self, address: Address, slot: U256, value: B256, ) -> impl Future<Output = RpcResult<()>> + Send

Writes a single position of an account’s storage.

fn hardhat_stop_impersonating_account( &self, address: Address, ) -> impl Future<Output = RpcResult<()>> + Send

Stops impersonating the given address.

Provided Methods

fn into_rpc(self) -> RpcModule<Self>

Collects all the methods and subscriptions defined in the trait and adds them into a single RpcModule.

Dyn Compatibility

This trait is not dyn compatible.

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