Pass feature flags to the underlying running rust code

[Acentelles]

I'm running mix test to test some rust code with rustler.

For this rust code to run, I need to pass the prove feature flag like this: cargo run -- --prove.

Is there a way to pass this feature flag with rustler?

mix test on a Rustler project will only ever run cargo build. If you mean cargo build --feature=prove, that is supported as a parameter on use Rustler.

What are you trying to do?

Hey! Thanks for your answer!

What are you trying to do?

I'm trying to run the rust code using the command flag prove (which can only be passed on run but not on build)

I tried something like this:
use Rustler, otp_app: :risc0, crate: :risc0_prover, features: :prove but it doesn't work.

Rustler doesn't run executables. It builds a library that is then loaded by the BEAM. There are no command-line flags.
