		### AOT Compilation
		### Custom `wizer` binary

		To enable AOT compilation, set the `enableAot: true` option to run [Weval][weval] ahead-of-time compilation.

		AOT compilation can also be configured with the following options:

		\| Option \| Type \| Example \| Description \|
		\|------------------------\|-------------------------------------\|-----------------\|--------------------------------------------------------------------------\|
		\| `aotMinStackSizeBytes` \| `nubmer \| Number \| bigint \| BigInt` \| `2_007_846_092` \| The minimum stack size (via `RUST_MIN_STACK` to set when running `weval` \|

		[weval]: https://github.com/bytecodealliance/weval

		### Custom `weval` binary for AOT

		To use a custom (pre-downloaded) [`weval`][weval] binary, set the `wevalBin` option to the path to your desired weval binary.

		### Custom `wizer` binary when AOT is disabled

		To use a custom (pre-downloaded) [`wizer`](https://github.com/bytecodealliance/wizer) binary, set the `wizerBin` option to the path to your desired wizer binary.
