Excuse me, and I ran the example's code, which is named toy_bn254.rs, with this terminal command "cargo run --release --example toy_bn254" in the toy directory. However, toy_bn254 seemed that the code couldn't open the toy.cpp or toy.wasm. Could you tell me how to solve this problem? Sorry, thanks.
Here is the error message I received.

As described in the README, you need to install circom and run the compile step for circuit (as in the CI setup as well:

  1. Install Circom
  2. Run examples/toy/compile.sh
