Parameters for configuring the rpc more granularity via CLI

Fields

http: bool

Enable the HTTP-RPC server

http_addr: IpAddr

Http server address to listen on

http_port: u16

Http server port to listen on

http_api: Option<RpcModuleSelection>

Rpc Modules to be configured for the HTTP server

http_corsdomain: Option<String>

Http Corsdomain to allow request from

ws: bool

Enable the WS-RPC server

ws_addr: IpAddr

Ws server address to listen on

ws_port: u16

Ws server port to listen on

ws_allowed_origins: Option<String>

Origins from which to accept WebSocket requests

ws_api: Option<RpcModuleSelection>

Rpc Modules to be configured for the WS server

ipcdisable: bool

Disable the IPC-RPC server

ipcpath: String

Filename for IPC socket/pipe within the datadir

auth_addr: IpAddr

Auth server address to listen on

auth_port: u16

Auth server port to listen on

auth_jwtsecret: Option<PathBuf>

Path to a JWT secret to use for the authenticated engine-API RPC server.

This will enforce JWT authentication for all requests coming from the consensus layer.

If no path is provided, a secret will be generated and stored in the datadir under <DIR>/<CHAIN_ID>/jwt.hex. For mainnet this would be ~/.reth/mainnet/jwt.hex by default.

auth_ipc: bool

Enable auth engine API over IPC

auth_ipc_path: String

Filename for auth IPC socket/pipe within the datadir

rpc_jwtsecret: Option<JwtSecret>

Hex encoded JWT secret to authenticate the regular RPC server(s), see --http.api and --ws.api.

This is not used for the authenticated engine-API RPC server, see --authrpc.jwtsecret.

rpc_max_request_size: MaxU32

Set the maximum RPC request payload size for both HTTP and WS in megabytes.

rpc_max_response_size: MaxU32

Set the maximum RPC response payload size for both HTTP and WS in megabytes.

rpc_max_subscriptions_per_connection: MaxU32

Set the maximum concurrent subscriptions per connection.

rpc_max_connections: MaxU32

Maximum number of RPC server connections.

rpc_max_tracing_requests: usize

Maximum number of concurrent tracing requests.

By default this chooses a sensible value based on the number of available cores. Tracing requests are generally CPU bound. Choosing a value that is higher than the available CPU cores can have a negative impact on the performance of the node and affect the node’s ability to maintain sync.

rpc_max_blocks_per_filter: ZeroAsNoneU64

Maximum number of blocks that could be scanned per filter request. (0 = entire chain)

rpc_max_logs_per_response: ZeroAsNoneU64

Maximum number of logs that can be returned in a single response. (0 = no limit)

rpc_gas_cap: u64

Maximum gas limit for eth_call and call tracing RPC methods.

rpc_max_simulate_blocks: u64

Maximum number of blocks for eth_simulateV1 call.

rpc_eth_proof_window: u64

The maximum proof window for historical proof generation. This value allows for generating historical proofs up to configured number of blocks from current tip (up to tip - window).

rpc_proof_permits: usize

Maximum number of concurrent getproof requests.

builder_disallow: Option<HashSet<Address>>

Path to file containing disallowed addresses, json-encoded list of strings. Block validation API will reject blocks containing transactions from these addresses.

rpc_state_cache: RpcStateCacheArgs

State cache configuration.

gas_price_oracle: GasPriceOracleArgs

Gas price oracle configuration.

Implementations

impl RpcServerArgs

pub const fn with_http(self) -> Self

Enables the HTTP-RPC server.

pub fn with_http_api(self, http_api: RpcModuleSelection) -> Self

Configures modules for the HTTP-RPC server.

pub const fn with_ws(self) -> Self

Enables the WS-RPC server.

pub const fn with_auth_ipc(self) -> Self

Enables the Auth IPC

pub fn adjust_instance_ports(&mut self, instance: u16)

Change rpc port numbers based on the instance number.

• The auth_port is scaled by a factor of instance * 100
• The http_port is scaled by a factor of -instance
• The ws_port is scaled by a factor of instance * 2
• The ipcpath is appended with the instance number: /tmp/reth.ipc-<instance>

Panics

Warning: if instance is zero in debug mode, this will panic.

This will also panic in debug mode if either:

• instance is greater than 655 (scaling would overflow u16)
• self.auth_port / 100 + (instance - 1) would overflow u16

In release mode, this will silently wrap around.

pub const fn with_http_unused_port(self) -> Self

Set the http port to zero, to allow the OS to assign a random unused port when the rpc server binds to a socket.

pub const fn with_ws_unused_port(self) -> Self

Set the ws port to zero, to allow the OS to assign a random unused port when the rpc server binds to a socket.

pub const fn with_auth_unused_port(self) -> Self

Set the auth port to zero, to allow the OS to assign a random unused port when the rpc server binds to a socket.

pub fn with_ipc_random_path(self) -> Self

Append a random string to the ipc path, to prevent possible collisions when multiple nodes are being run on the same machine.

pub fn with_unused_ports(self) -> Self

Configure all ports to be set to a random unused port when bound, and set the IPC path to a random path.

Trait Implementations

impl Args for RpcServerArgs

fn group_id() -> Option<Id>

Report the [ArgGroup::id][crate::ArgGroup::id] for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to [Command] so it can instantiate Self via [FromArgMatches::from_arg_matches_mut]

fn augment_args_for_update<'b>(__clap_app: Command) -> Command

Append to [Command] so it can instantiate self via [FromArgMatches::update_from_arg_matches_mut]

impl Clone for RpcServerArgs

fn clone(&self) -> RpcServerArgs

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RpcServerArgs

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RpcServerArgs

fn default() -> Self

Returns the “default value” for a type.

impl FromArgMatches for RpcServerArgs

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<Self, Error>

Instantiate Self from [ArgMatches], parsing the arguments as needed.

fn from_arg_matches_mut( __clap_arg_matches: &mut ArgMatches, ) -> Result<Self, Error>

Instantiate Self from [ArgMatches], parsing the arguments as needed.

fn update_from_arg_matches( &mut self, __clap_arg_matches: &ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

fn update_from_arg_matches_mut( &mut self, __clap_arg_matches: &mut ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

impl PartialEq for RpcServerArgs

fn eq(&self, other: &RpcServerArgs) -> 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 Eq for RpcServerArgs

impl StructuralPartialEq for RpcServerArgs
