Any example of using reth's client?

[Pzixel]

I'm currently use alloy for my RPC needs, but sometimes some APis are only supported by reth, and do not exist in alloy while I know that the underlying protocols actually supports it. I can see that reth can generate an RPC client that can be used to perform actual requests: there is a client feature on a reth-rpc-eth-api crate. However, I haven't succeeded with properly using the jsonrpsee to make it work. If there any examples that use that it would help a great deal. The main question if there are any existing good types to replace all those generics <TxReq: RpcObject, T: RpcObject, B: RpcObject, R: RpcObject, H: RpcObject> with

Here is the API I'm talking about:

reth/crates/rpc/rpc-eth-api/src/core.rs

Line 51 in 4cc50f9

#[cfg_attr(feature = "client", rpc(server, client, namespace = "eth"))]

I think I've answered my question:

use alloy::eips::BlockNumberOrTag;
use alloy::network::Ethereum;
use alloy::network::Network;
use jsonrpsee::http_client::HttpClient;

#[tokio::main]
async fn main() {
    let client =  HttpClient::builder()
        .build("RPC_URL")
        .unwrap();

    type TxReq = <Ethereum as Network>::TransactionRequest;
    type T = <Ethereum as Network>::TransactionResponse;
    type B = <Ethereum as Network>::BlockResponse;
    type R = <Ethereum as Network>::ReceiptResponse;
    type H = <Ethereum as Network>::HeaderResponse;

    let result = <HttpClient as reth_rpc_api::EthApiClient<TxReq, T, B, R, H>>::block_by_number(
        &client,
        BlockNumberOrTag::Pending,
        false,
        ).await.unwrap();
    println!("result: {:#?}", result.unwrap().header);
}

yeah these client traits are mainly only useful when doing like e2e testing via the generics

Well I meant using it for real RPC in production. Because if you look at this exact block_by_number in allloy - it doesn't have the last isFull: bool argument. So there is just no way you can do it with their API. So you have to either construct a low level request manually or use reth's RPC.
