Class `std.uuid.UUIDParsingException`

This exception is thrown if an error occurs when parsing a UUID from a string.


						
				class UUIDParsingException
				
  : Exception
				;

Fields

Name	Type	Description
`input`	`string`	The original input string which should have been parsed.
`position`	`ulong`	The position in the input string where the error occurred.
`reason`	`UUIDParsingException.Reason`	The reason why parsing the UUID string failed (if known)
`file`	`string`	The file name of the D source code corresponding with where the error was thrown from.
`info`	`object.Throwable.TraceInfo`	The stack trace of where the error happened. This is an opaque object that can either be converted to `string`, or iterated over with `foreach` to extract the items in the stack trace (as strings).
`infoDeallocator`	`nothrow void function(object.Throwable.TraceInfo)`	If set, this is used to deallocate the TraceInfo on destruction.
`line`	`ulong`	The line number of the D source code corresponding with where the error was thrown from.
`msg`	`string`	A message describing the error.

Properties

Name	Type	Description
`next`[get]	`inout(Throwable)`
`next`[set]	`Throwable`	Replace next in chain with `tail`. Use `chainTogether` instead if at all possible.

Methods

Name	Description
`chainTogether` ()	Append `e2` to chain of exceptions that starts with `e1`.
`factory` (classname)	Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor.
`message` ()	Get the message describing the error.
`opApply` (dg)	Loop over the chain of Throwables.
`opCmp` (o)	Compare with another Object obj.
`opEquals` (o)	Test whether `this` is equal to `o`. The default implementation only compares by identity (using the `is` operator). Generally, overrides and overloads for `opEquals` should attempt to compare objects by their contents. A class will most likely want to add an overload that takes your specific type as the argument and does the content comparison. Then you can override this and forward it to your specific typed overload with a cast. Remember to check for `null` on the typed overload.
`refcount` ()
`toHash` ()	Compute hash function for Object.
`toString` ()	Overrides `Object.toString` and returns the error message. Internally this forwards to the `toString` overload that takes a sink delegate.
`toString` ()	The Throwable hierarchy uses a toString overload that takes a sink delegate to avoid GC allocations, which cannot be performed in certain error situations. Override this `toString` method to customize the error message.

Enums

Name	Description
`Reason`	The reason why parsing the UUID string failed (if known)

Example

import std.exception : collectException;

const inputUUID = "this-is-an-invalid-uuid";
auto ex = collectException!UUIDParsingException(UUID(inputUUID));
assert(ex !is null); // check that exception was thrown
writeln(ex.input); // inputUUID
writeln(ex.position); // 0
writeln(ex.reason); // UUIDParsingException.Reason.tooLittle
