Struct alloy_node_bindings::nodes::reth::Reth

pub struct Reth { /* private fields */ }

Builder for launching reth.

Panics

If spawn is called without reth being available in the user’s $PATH

Example

use alloy_node_bindings::Reth;

let port = 8545u16;
let url = format!("http://localhost:{}", port).to_string();

let reth = Reth::new().instance(1).block_time("12sec").spawn();

drop(reth); // this will kill the instance

Implementations

impl Reth

pub fn new() -> Self

Creates an empty Reth builder.

The instance number is set to a random number between 1 and 200 by default to reduce the odds of port conflicts. This can be changed with Reth::instance. Set to 0 to use the default ports. 200 is the maximum number of instances that can be run set by Reth.

pub fn at(path: impl Into<PathBuf>) -> Self

Creates a Reth builder which will execute reth at the given path.

Example

use alloy_node_bindings::Reth;
let reth = Reth::at("../reth/target/release/reth").spawn();

println!("Reth running at `{}`", reth.endpoint());

pub fn path<T: Into<PathBuf>>(self, path: T) -> Self

Sets the path to the reth executable

By default, it’s expected that reth is in $PATH, see also std::process::Command::new()

pub const fn dev(self) -> Self

Enable dev mode for the Reth instance.

pub const fn http_port(self, http_port: u16) -> Self

Sets the HTTP port for the Reth instance. Note: this resets the instance number to 0 to allow for custom ports.

pub const fn ws_port(self, ws_port: u16) -> Self

Sets the WS port for the Reth instance. Note: this resets the instance number to 0 to allow for custom ports.

pub const fn auth_port(self, auth_port: u16) -> Self

Sets the auth port for the Reth instance. Note: this resets the instance number to 0 to allow for custom ports.

pub const fn p2p_port(self, p2p_port: u16) -> Self

Sets the p2p port for the Reth instance. Note: this resets the instance number to 0 to allow for custom ports.

pub fn block_time(self, block_time: &str) -> Self

Sets the block time for the Reth instance. Parses strings using https://docs.rs/humantime/latest/humantime/fn.parse_duration.html This is only used if dev mode is enabled.

pub const fn disable_discovery(self) -> Self

Disables discovery for the Reth instance.

pub fn chain_or_path(self, chain_or_path: &str) -> Self

Sets the chain id for the Reth instance.

pub const fn enable_ipc(self) -> Self

Enable IPC for the Reth instance.

pub const fn instance(self, instance: u16) -> Self

Sets the instance number for the Reth instance. Set to 0 to use the default ports. By default, a random number between 1 and 200 is used.

pub fn ipc_path<T: Into<PathBuf>>(self, path: T) -> Self

Sets the IPC path for the socket.

pub fn data_dir<T: Into<PathBuf>>(self, path: T) -> Self

Sets the data directory for reth.

pub fn genesis(self, genesis: Genesis) -> Self

Sets the genesis.json for the Reth instance.

If this is set, reth will be initialized with reth init and the --datadir option will be set to the same value as data_dir.

This is destructive and will overwrite any existing data in the data directory.

pub fn arg<T: Into<OsString>>(self, arg: T) -> Self

Adds an argument to pass to reth.

Pass any arg that is not supported by the builder.

pub fn args<I, S>(self, args: I) -> Self

where I: IntoIterator<Item = S>, S: Into<OsString>,

Adds multiple arguments to pass to reth.

Pass any args that is not supported by the builder.

pub fn spawn(self) -> RethInstance

Consumes the builder and spawns reth.

Panics

If spawning the instance fails at any point.

pub fn try_spawn(self) -> Result<RethInstance, NodeError>

Consumes the builder and spawns reth. If spawning fails, returns an error.

Trait Implementations

Performs copy-assignment from source.

impl Debug for Reth

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

impl Default for Reth

fn default() -> Reth

Returns the “default value” for a type.
