25 // Helper functions that allow throwing exceptions consistently from anywhere.
26 // The main use case is for header-based libraries (eg templates), as they will
27 // be built by many different targets with their own compiler options.
28 // In particular, this will allow a safe way to throw exceptions even if the
29 // caller is compiled with -fno-exceptions. This is intended for implementing
30 // things like map<>::at(), which the standard documents as throwing an
31 // exception on error.
32 //
33 // Using other techniques like #if tricks could lead to ODR violations.
34 //
35 // You shouldn't use it unless you're writing code that you know will be built
36 // both with and without exceptions and you need to conform to an interface
37 // that uses exceptions.
