Objective

  • Audio wants a realtime-safe executor with minimal checking. This means no command application or multithreading etc.

Solution

  • Make it possible to supply our own executor.

Testing

  • Tests are updated
  • New custom executor example

Note: reviewing commits individually is probably easier.

The generated examples/README.md is out of sync with the example metadata in Cargo.toml or the example readme template. Please run cargo run -p build-templated-pages -- update examples to update it, and commit the file change.
