E4070

Unknown intrinsic. This intrinsic is not known to the MoonBit compiler.

Intrinsics are not intended for usage outside of moonbitlang/core. They are subject to change without notice, and we highly recommend against using them.

Erroneous example

///|
pub fn my_abort(message : String) -> Unit = "%abort"
// Error: Unknown intrinsic: %abort

Suggestion

You probably want to use the abort function from moonbitlang/core:

///|
pub fn my_abort(message : String) -> Unit {
  abort(message)
}

If you really need to use the intrinsic, you can check the source code of moonbitlang/core for further usage of the corresponding intrinsic.
