// Helper functions that allow throwing exceptions consistently from anywhere.

// The main use case is for header-based libraries (eg templates), as they will
|
||
|
|
// be built by many different targets with their own compiler options.
|
||
|
|
// In particular, this will allow a safe way to throw exceptions even if the
|
||
|
|
// caller is compiled with -fno-exceptions. This is intended for implementing
|
||
|
|
// things like map<>::at(), which the standard documents as throwing an
|
||
|
|
// exception on error.
|
||
|
|
//
|
||
|
|
// Using other techniques like #if tricks could lead to ODR violations.

// You shouldn't use it unless you're writing code that you know will be built
|

// both with and without exceptions and you need to conform to an interface

// that uses exceptions.
