[−][src]Enum arithmetic_eval::error::ErrorKind
Kinds of errors that can occur when compiling or interpreting expressions and statements.
Variants (Non-exhaustive)
Mismatch between length of tuples in a binary operation or assignment.
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.
Mismatch between the number of arguments in the function definition and its call.
Fields of ArgsLenMismatch
Cannot destructure a non-tuple variable.
Repeated assignment to the same variable in function args or tuple destructuring.
Fields of RepeatedAssignment
context: RepeatedAssignmentContext
Context in which the error has occurred.
Undefined(String)
Variable with the enclosed name is not defined.
Value is not callable (i.e., is not a function).
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.
Fields of UnexpectedOperand
op: Op
Operation which failed.
Value cannot be compared to other values. Only numbers can be compared; other value types cannot.
Unexpected result of a comparison function invocation. The comparison function should always return -1, 0, or 1.
Unsupported(UnsupportedType)
Construct not supported by the interpreter.
Arithmetic(ArithmeticError)
Arithmetic
error, such as division by zero.
Implementations
impl ErrorKind
[src]
pub fn native(message: impl Into<String>) -> Self
[src]

pub fn to_short_string(&self) -> String
[src]
Returned shortened error cause.
pub fn main_span_info(&self) -> String
[src]
Returns a short description of the spanned information.
pub fn help(&self) -> Option<String>
[src]
Returns information helping fix the error.
