// 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. |
