Cannot use rust to invoke in3 because of an error "failed to resolve: use of undeclared type BlockNumber"

[a3845]

Steps to reproduce

I am trying to use the Ethereum contract call code here: https://in3.readthedocs.io/en/develop/api-rust.html#an-ethereum-contract-call

When I execute "cargo run" with the code above, I get an error.

Expected behavior

I expect cargo run to complete without an error.

Actual behavior

error[E0433]: failed to resolve: use of undeclared type BlockNumber
--> /home/foobar/rust/good.rs:22:42
|
22 | task::block_on(eth_api.call(txn, BlockNumber::Latest)).expect("ETH call failed");
| ^^^^^^^^^^^ use of undeclared type BlockNumber

I see no missing dependency error; I have seen Cargo throw errors for such things. I cannot use in3 0.0.2 instead of 0.1.7 because this unsolved bug: rust-lang/rust#80948
The problem is reproducible when I try to use in3 0.1.6.

System configuration

I have Rust 1.49 installed. I have Cargo 1.49 installed too.

Incubed version

0.1.7

Thanks for the feedback! Can you try building the in3-example-rust project on your system? This way we can rule out the possibility of toolchain problems. Also, make sure to check out other requirements on in3-rs's crates.io page.

in3-example-rust allowed me to run "cargo run".

I just updated the documentation and also 3 days ago the Version 0.1.8 was released. I think in your code you are just missing those imports:

use in3::eth1::*;
