- class
RangeError: object.Error; - Thrown on a range error.
- class
AssertError: object.Error; - Thrown on an assert error.
- class
FinalizeError: object.Error; - Thrown on finalize error.
- class
OutOfMemoryError: object.Error; - Thrown on an out of memory error.
- class
InvalidMemoryOperationError: object.Error; - Thrown on an invalid memory operation.An invalid memory operation error occurs in circumstances when the garbage collector has detected an operation it cannot reliably handle. The default D GC is not re-entrant, so this can happen due to allocations done from within finalizers called during a garbage collection cycle.
- class
SwitchError: object.Error; - Thrown on a switch error.
- class
UnicodeException: object.Exception; - Thrown on a unicode conversion error.

AssertHandler= void function(string file, uint line, string msg) nothrow;
nothrow @nogc @property @trusted AssertHandlerassertHandler();
nothrow @nogc @property @trusted voidassertHandler(AssertHandlerhandler); - Gets/sets assert hander. null means the default handler is used.
- nothrow void
onAssertError(stringfile= __FILE__, size_tline= __LINE__); - A callback for assert errors in D. The user-supplied assert handler will be called if one has been supplied, otherwise an AssertError will be thrown.Parameters:
string fileThe name of the file that signaled this error. size_t lineThe line number on which this error occurred. - nothrow void
onAssertErrorMsg(stringfile, size_tline, stringmsg); - A callback for assert errors in D. The user-supplied assert handler will be called if one has been supplied, otherwise an AssertError will be thrown.Parameters:
string fileThe name of the file that signaled this error. size_t lineThe line number on which this error occurred. string msgAn error message supplied by the user. - nothrow void
onUnittestErrorMsg(stringfile, size_tline, stringmsg); - A callback for unittest errors in D. The user-supplied unittest handler will be called if one has been supplied, otherwise the error will be written to stderr.Parameters:
string fileThe name of the file that signaled this error. size_t lineThe line number on which this error occurred. string msgAn error message supplied by the user. - pure nothrow @nogc @trusted void
onRangeError(stringfile= __FILE__, size_tline= __LINE__); - A callback for array bounds errors in D. A RangeError will be thrown.Parameters:
string fileThe name of the file that signaled this error. size_t lineThe line number on which this error occurred. Throws: - nothrow @trusted void
onFinalizeError(TypeInfoinfo, Throwablee, stringfile= __FILE__, size_tline= __LINE__); - A callback for finalize errors in D. A FinalizeError will be thrown.Parameters:
TypeInfo infoThe TypeInfo instance for the object that failed finalization. Throwable eThe exception thrown during finalization. string fileThe name of the file that signaled this error. size_t lineThe line number on which this error occurred. Throws: - pure nothrow @nogc @trusted void
onOutOfMemoryError(void*pretend_sideffect= null); - A callback for out of memory errors in D. An OutOfMemoryError will be thrown.Throws:
- pure nothrow @nogc @trusted void
onInvalidMemoryOperationError(void*pretend_sideffect= null); - A callback for invalid memory operations in D. An InvalidMemoryOperationError will be thrown.Throws:
- pure @safe void
onUnicodeError(stringmsg, size_tidx, stringfile= __FILE__, size_tline= __LINE__); - A callback for unicode errors in D. A UnicodeException will be thrown.Parameters:
string msgInformation about the error. size_t idxString index where this error was detected. string fileThe name of the file that signaled this error. size_t lineThe line number on which this error occurred. Throws: - void
