Utility to run a liquidregtest elementsd process, useful in integration testing environment.

use elementsd::bitcoincore_rpc::RpcApi;
let exe = elementsd::exe_path().expect("elementsd executable must be provided in ELEMENTSD_EXE, or with a feature like '0_21_0', or be in PATH");
let elementsd = elementsd::ElementsD::new(exe).unwrap();
let info = elementsd
    .client()
    .call::<bitcoind::bitcoincore_rpc::jsonrpc::serde_json::Value>("getblockchaininfo", &[])
    .unwrap();
assert_eq!(info.get("chain").unwrap(), "liquidregtest");

You can also start elementsd with validate pegin capability by connecting an instance of bitcoind. See test test_elementsd_with_validatepegin

See the similar BitcoinD for details

For determinisim, in nix you cannot hit the internet within the build.rs. Moreover, some downstream crates cannot remove the auto-download feature from their dev-deps. In this case you can set the ELEMENTSD_SKIP_DOWNLOAD env var and provide the elementsd executable in the PATH (or skip the test execution).

To build docs:

RUSTDOCFLAGS="--cfg docsrs" cargo +nightly doc --features download,doc --open

• 1.57.0 with one of the auto download features
• 1.56.1 without features

MSRV 1.56.1 may require downgrading dependencies. See our .github/workflows/test.yml file for a complete list.
