Description

Problem*

Resolves

Summary*

Any low-level functions don't have a function implementation in Noir so all inputs will appear unused. We currently prefix these arguments with underscores to silence this but this leaks through into the docs where preferably we'd have non-underscored variables.

This also affects any oracle functions which may exist in user code, requiring them to use underscores in the same way which isn't ideal.

This PR then disables unused variable checks on any function with the #[foreign], #[builtin] or #[oracle] attributes.

Additional Context

Documentation*

Check one:

  • No documentation needed.
  • Documentation included in this PR.
  • [Exceptional Case] Documentation to be submitted in a separate PR.

PR Checklist*

  • I have tested the changes locally.
  • I have formatted the changes with Prettier and/or cargo fmt on default settings.
