Error in derive macro NetworkBehaviour

[Slava2001]

Summary

The code below does not compile:

use error_stack::Result;
use libp2p::{gossipsub, swarm::NetworkBehaviour};

#[derive(NetworkBehaviour)]
struct MyBehaviour {
    gossipsub: gossipsub::Behaviour,
}

fn main() {
    println!("Hello, world!");
}

This happens because use error_stack::Result; redefines Result and the code generated by the macro #[derive(NetworkBehaviour)] becomes invalid.

Expected behavior

The code should compile.

Actual behavior

The code does not compile.

Relevant log output

error[E0308]: mismatched types
 --> src\main.rs:4:10

  |          ^^^^^^^^^^^^^^^^
  |          |
  |          expected `Result<(), ...>`, found `Result<(), Error>`
  |          expected `Result<(), error_stack::Report<std::fmt::Error>>` because of return type

  = note: expected enum `Result<_, error_stack::Report<std::fmt::Error>>`
             found enum `Result<_, std::fmt::Error>`

Possible Solution

Replace the Result in the ./swarm-derive/src/lib.rs file with std::result::Result.
