  • location (Optional): The location of the error (defaults to call_location).

Raises:

An Error with the provided message if assert fails and None otherwise.

assert_equal[O1: Origin[mut=mut], O2: Origin[mut=mut]](lhs: List[StringSlice[O1]], rhs: List[StringSlice[O2]], msg: String = "", *, location: Optional[SourceLocation] = None)

Asserts that two lists are equal.

Parameters:
