Source Edit Exception and effect types used in Nim code.
Types
AccessViolationDefect = object of Defect
- Raised for invalid memory access errors Source Edit
AccessViolationError {....deprecated: "See corresponding Defect".} = AccessViolationDefect-
Deprecated: See corresponding Defect

Note: Nim currently does not detect these!

Raised by 0.0/0.0, for example.
Source Edit FloatInvalidOpError {....deprecated: "See corresponding Defect".} = FloatInvalidOpDefect-
Deprecated: See corresponding Defect
Source Edit FloatOverflowDefect = object of FloatingPointDefect
-

The operation produced a result that exceeds the range of the exponent.
Source Edit FloatOverflowError {....deprecated: "See corresponding Defect".} = FloatOverflowDefect-
Deprecated: See corresponding Defect
Source Edit FloatUnderflowDefect = object of FloatingPointDefect
-
Raised for underflows.
The operation produced a result that is too small to be represented as a normal number.

KeyError = object of ValueError
-
Raised if a key cannot be found in a table.
Mostly used by the tables module, it can also be raised by other collection modules like sets or strtabs.
Source Edit LibraryError = object of OSError
- Raised if a dynamic library could not be loaded. Source Edit

ObjectAssignmentError {....deprecated: "See corresponding Defect".} = ObjectAssignmentDefect-
Deprecated: See corresponding Defect
Source Edit ObjectConversionDefect = object of Defect
- Raised if an object is converted to an incompatible object type. You can use
of operator to check if conversion will succeed. Source Edit ObjectConversionError {....deprecated: "See corresponding Defect".} = ObjectConversionDefect-
Deprecated: See corresponding Defect
Source Edit OSError = object of CatchableError
errorCode*: int32 ## OS-defined error code describing this error.
