## Run simulator using the Miri interpreter
Miri is a deterministic Rust interpreter designed to identify undefined behavior. To run the simulator under Miri, use
```bash
MIRIFLAGS="-Zmiri-disable-isolation -Zmiri-disable-stacked-borrows" RUST_LOG=limbo_sim=debug cargo +nightly miri run --bin limbo_sim -- --disable-integrity-check
````
Notes:
- `-Zmiri-disable-isolation` is needed for host access (like opening a file)
- `-Zmiri-disable-stacked-borrows` this alias checking is experimental, so disabled for now
- `--disable-integrity-check` is needed since we can't run sqlite via the FFI in Miri
