Struct ethers_core::utils::Ganache

pub struct Ganache { /* private fields */ }

Builder for launching ganache-cli.

Panics

If spawn is called without ganache-cli being available in the user’s $PATH

Example

use ethers_core::utils::Ganache;

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

let ganache = Ganache::new()
    .port(port)
    .mnemonic("abstract vacuum mammal awkward pudding scene penalty purchase dinner depart evoke puzzle")
    .spawn();

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

Implementations

impl Ganache

pub fn new() -> Self

Creates an empty Ganache builder. The default port is 8545. The mnemonic is chosen randomly.

pub fn startup_timeout_millis<T: Into<u64>>(self, timeout: T) -> Self

Sets the startup timeout which will be used when the ganache-cli instance is launched in miliseconds. 10_000 miliseconds by default).

pub fn port<T: Into<u16>>(self, port: T) -> Self

Sets the port which will be used when the ganache-cli instance is launched.

pub fn mnemonic<T: Into<String>>(self, mnemonic: T) -> Self

Sets the mnemonic which will be used when the ganache-cli instance is launched.

pub fn block_time<T: Into<u64>>(self, block_time: T) -> Self

Sets the block-time which will be used when the ganache-cli instance is launched.

pub fn fork<T: Into<String>>(self, fork: T) -> Self

Sets the fork argument to fork from another currently running Ethereum client at a given block. Input should be the HTTP location and port of the other client, e.g. http://localhost:8545. You can optionally specify the block to fork from using an @ sign: http://localhost:8545@1599200

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

Adds an argument to pass to the ganache-cli.

pub fn args<I, S>(self, args: I) -> Self where
    I: IntoIterator<Item = S>,
    S: Into<String>, 

Adds multiple arguments to pass to the ganache-cli.

pub fn spawn(self) -> GanacheInstance

Consumes the builder and spawns ganache-cli with stdout redirected to /dev/null. This takes ~2 seconds to execute as it blocks while waiting for ganache-cli to launch.
