Cannot connect to client: Transport("SendError(\"...\")") about rust-web3 HOT 8 CLOSED

Do you have the node running in the background?

from rust-web3.

Yes, it's instance=Geth/v1.7.2-stable-1db4ecdc/darwin-amd64/go1.9.1 started with

geth --testnet --bootnodes "enode://20c9ad97c081d63397d7b685a412227a40e23c8bdc6688c6f37e97cfbc22d2b4d1db1510d8f61e6a8866ad7f0e17c02b14182d37ea7c3c8b9c2683aeb6b733a1@52.169.14.227:30303,enode://6ce05930c72abc632c58e2e4324f7c7ea478cec0ed4fa2528982cf34483094e9cbc9216e7aa349691242576d552a2a56aaeae426c5303ded677ce455ba1acd9d@13.84.180.240:30303" --rpcapi eth,web3,net,debug,personal --rpc

from rust-web3.

Can you see the request arriving at the geth node? Can you run with some tracing?

Also could you change the code and display the details of the error:

let accounts = web3.eth().accounts().wait().unwrap_err();
println!("{:?"}, accounts);

from rust-web3.

With unwrap_err the error looks like that:

Accounts: Transport(
    "SendError(\"...\")"
)

Do you know what log level I need in geth to see arriving requests? On level 4 I don't see any requests and on level 5 it's way to much output.

from rust-web3.

SendError suggests that web3 is not even able to reach the node (so that's why you might not see anything in the logs).
Make sure that address/port is correct and the node is running and have RPC enabled.

from rust-web3.

The issue seems to be that I used

let (_, http) = web3::transports::Http::new("http://localhost:8545").unwrap();

instead of

let (_eloop, http) = web3::transports::Http::new("http://localhost:8545").unwrap();

Does every value assigned to _ get dropped directly?

from rust-web3.

Indeed _ can be dropped right away, _anything is dropped when it goes out of scope

from rust-web3.

Ok, thanks for the explanation.
