Expand description
Kinds of errors that can occur when compiling or interpreting expressions and statements.
Variants (Non-exhaustive)
This enum is marked as non-exhaustive
Mismatch between length of tuples in a binary operation or assignment.
Show fields
Fields of TupleLenMismatch
lhs: LvalueLen
Length of a tuple on the left-hand side.
rhs: usize
Length of a tuple on the right-hand side.
context: TupleLenMismatchContext
Context in which the error has occurred.
Field set differs between LHS and RHS, which are both objects.
Show fields
Mismatch between the number of arguments in the function definition and its call.
Show fields
Cannot destructure a non-tuple variable.
Repeated assignment to the same variable in function args or tuple destructuring.
Show fields
Fields of RepeatedAssignment
context: RepeatedAssignmentContext
Context in which the error has occurred.
Repeated field in object initialization (e.g., #{ x: 1, x: 2 }
) or destructure
(e.g., { x, x }
).
Undefined(String)
Variable with the enclosed name is not defined.
InvalidFieldName(String)
Field name is invalid.
Value is not callable (i.e., it is not a function).
Value cannot be indexed (i.e., it is not a tuple).
A field cannot be accessed for the value (i.e., it is not an object).
Index is out of bounds for the indexed tuple.
Object does not have a required field.
Show fields
NativeCall(String)
Generic error during execution of a native function.
Wrapper(FromValueError)
Error while converting arguments for FnWrapper
.
Unexpected operand type for the specified operation.
Show fields
Fields of UnexpectedOperand
op: Op
Operation which failed.
Value cannot be compared to other values. Only primitive values can be compared; other value types cannot.
Unsupported(UnsupportedType)
Construct not supported by the interpreter.
Arithmetic(ArithmeticError)
Arithmetic
error, such as division by zero.
