Parity-specific rpc interface for operations altering the settings.

## Required Methods

### `fn set_min_gas_price(&self, U256) -> Result<bool, Error>`

Sets new minimal gas price for mined blocks.

### `fn set_gas_floor_target(&self, U256) -> Result<bool, Error>`

Sets new gas floor target for mined blocks.

### `fn set_gas_ceil_target(&self, U256) -> Result<bool, Error>`

Sets new gas ceiling target for mined blocks.

### `fn set_extra_data(&self, Bytes) -> Result<bool, Error>`

Sets new extra data for mined blocks.

### `fn set_author(&self, H160) -> Result<bool, Error>`

Sets new author for mined block.

### `fn set_engine_signer(&self, H160, String) -> Result<bool, Error>`

Sets account for signing consensus messages.

### `fn set_transactions_limit(&self, usize) -> Result<bool, Error>`

Sets the limits for transaction queue.

### `fn set_tx_gas_limit(&self, U256) -> Result<bool, Error>`

Sets the maximum amount of gas a single transaction may consume.

### `fn add_reserved_peer(&self, String) -> Result<bool, Error>`

Add a reserved peer.

### `fn remove_reserved_peer(&self, String) -> Result<bool, Error>`

Remove a reserved peer.

### `fn drop_non_reserved_peers(&self) -> Result<bool, Error>`

Drop all non-reserved peers.

### `fn accept_non_reserved_peers(&self) -> Result<bool, Error>`

Accept non-reserved peers (default behavior)

### `fn start_network(&self) -> Result<bool, Error>`

Start the network.

Deprecated. Use `set_mode("active")` instead.

### `fn stop_network(&self) -> Result<bool, Error>`

Stop the network.

Deprecated. Use `set_mode("offline")` instead.

### `fn set_mode(&self, String) -> Result<bool, Error>`

Set the mode. Argument must be one of: "active", "passive", "dark", "offline".

### `fn hash_content(&self, String) -> BoxFuture<H256, Error>`

Hash a file content under given URL.

### `fn upgrade_ready(&self) -> Result<Option<ReleaseInfo>, Error>`

Is there a release ready for install?

### `fn execute_upgrade(&self) -> Result<bool, Error>`

Execute a release which is ready according to upgrade_ready().

## Provided Methods

### `fn to_delegate<M: Metadata>(self) -> IoDelegate<Self, M>`

Transform this into an `IoDelegate`, automatically wrapping the parameters.

## Implementors

- `impl<C, M, U, F> ParitySet for ParitySetClient<C, M, U, F> where C: MiningBlockChainClient + 'static, M: MinerService + 'static, U: UpdateService + 'static, F: Fetch + 'static`

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
