- 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, ulong 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 file
The name of the file that signaled this error. size_t line
The 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 file
The name of the file that signaled this error. size_t line
The line number on which this error occurred. string msg
An 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 file
The name of the file that signaled this error. size_t line
The line number on which this error occurred. string msg
An 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 file
The name of the file that signaled this error. size_t line
The 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 info
The TypeInfo instance for the object that failed finalization. Throwable e
The exception thrown during finalization. string file
The name of the file that signaled this error. size_t line
The 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 msg
Information about the error. size_t idx
String index where this error was detected. string file
The name of the file that signaled this error. size_t line
The line number on which this error occurred. Throws: - void
