Renaming Sway imports causes abigen!() macro to fail

Author: soltheonCreated Nov 25, 2025Updated Nov 25, 2025

I am trying to import PoolId from Mira and Reactor exchanges, so I renamed one like this:

use interfaces::{data_structures::PoolId, mira_amm::MiraAMM};
use reactor_interfaces::{reactor_pool::ReactorPool, data_structures::PoolId as ReactorPoolId};

....this compiles successfully with forc, but when I try to use the script in fuels-rs it fails to find that type:

error[E0412]: cannot find type `ReactorPoolId` in this scope
  --> bin/reactor_arbitrage.rs:20:1
   |
20 | / abigen!(Script(
21 | |     name = "SimulationScript",
22 | |     abi = "./sway/scripts/simulate_reactor/out/release/simulate_reactor-abi.json"
23 | | ));
   | |__^ not found in this scope
   |
   = note: this error originates in the macro `abigen` (in Nightly builds, run with -Z macro-backtrace for more info)

fuels = { version = "0.76.0", features=["std", "coin-cache"] } forc 0.70.1
