Types

AccessViolationDefect = object of Defect

Raised for invalid memory access errors Source   Edit  

ArithmeticDefect = object of Defect

Raised if any kind of arithmetic error occurred. Source   Edit  

AssertionDefect = object of Defect

Raised when assertion is proved wrong.

Usually the result of using the assert() template.

Source   Edit  

DeadThreadDefect = object of Defect

Raised if it is attempted to send a message to a dead thread. Source   Edit  

DivByZeroDefect = object of ArithmeticDefect

Raised for runtime integer divide-by-zero errors. Source   Edit  

EOFError = object of IOError

Raised if an IO "end of file" error occurred. Source   Edit  

ExecIOEffect = object of IOEffect

Effect describing an executing IO operation. Source   Edit  

FieldDefect = object of Defect

Raised if a record field is not accessible because its discriminant's value does not fit. Source   Edit  

FloatDivByZeroDefect = object of FloatingPointDefect

Raised by division by zero.

Divisor is zero and dividend is a finite nonzero number.

Source   Edit  

FloatInexactDefect = object of FloatingPointDefect

Raised for inexact results.

The operation produced a result that cannot be represented with infinite precision -- for example: 2.0 / 3.0, log(1.1)

Note: Nim currently does not detect these!

Source   Edit  

FloatingPointDefect = object of Defect

Base class for floating point exceptions. Source   Edit  

FloatInvalidOpDefect = object of FloatingPointDefect

Raised by invalid operations according to IEEE.

Raised by 0.0/0.0, for example.

Source   Edit  

FloatOverflowDefect = object of FloatingPointDefect

Raised for overflows.

The operation produced a result that exceeds the range of the exponent.

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.

Source   Edit  

IndexDefect = object of Defect

Raised if an array index is out of bounds. Source   Edit  

IOEffect = object of RootEffect

IO effect. Source   Edit  

IOError = object of CatchableError

Raised if an IO error occurred. Source   Edit  

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  

NilAccessDefect = object of Defect

Raised on dereferences of nil pointers.

This is only raised if the segfaults module was imported!

Source   Edit  

ObjectAssignmentDefect = object of Defect

Raised if an object gets assigned to its parent's object. 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  

OSError = object of CatchableError
  errorCode*: int32          ## OS-defined error code describing this error.
  

Raised if an operating system service failed. Source   Edit  

OutOfMemDefect = object of Defect

Raised for unsuccessful attempts to allocate memory. Source   Edit  

OverflowDefect = object of ArithmeticDefect

Raised for runtime integer overflows.

This happens for calculations whose results are too large to fit in the provided bits.

Source   Edit  

RangeDefect = object of Defect

Raised if a range check error occurred. Source   Edit  

ReadIOEffect = object of IOEffect

Effect describing a read IO operation. Source   Edit  

ReraiseDefect = object of Defect

Raised if there is no exception to reraise. Source   Edit  

ResourceExhaustedError = object of CatchableError

Raised if a resource request could not be fulfilled. Source   Edit  

StackOverflowDefect = object of Defect

Raised if the hardware stack used for subroutine calls overflowed. Source   Edit  

TimeEffect = object of RootEffect

Time effect. Source   Edit  

ValueError = object of CatchableError

Raised for string and object conversion errors. Source   Edit  

WriteIOEffect = object of IOEffect

Effect describing a write IO operation. Source   Edit
