E4070

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

Note all intrinsic is not intended for usage outside of moonbitlang/core and is 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

fn main {
  my_abort("Abort!")
}

Suggestion

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

fn main {
  abort("Abort!")
}

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