// Behavioral setup (error handling macro configuration)
//*****************************************************************************
// Set any of the following macros to the values given below before including Result.h to
// control the error handling macro's trade-offs between diagnostics and performance
// RESULT_DIAGNOSTICS_LEVEL
// This define controls the level of diagnostic instrumentation that is built into the binary as a
// byproduct of using the macros. The amount of diagnostic instrumentation that is supplied is
// a trade-off between diagnosibility of issues and code size and performance. The modes are:
// 0 - No diagnostics, smallest & fastest (subject to tail-merge)
// 1 - No diagnostics, unique call sites for each macro (defeat's tail-merge)
// 2 - Line number
// 3 - Line number + source filename
// 4 - Line number + source filename + function name
// 5 - Line number + source filename + function name + code within the macro
// By default, mode 3 is used in free builds and mode 5 is used in checked builds. Note that the
// _ReturnAddress() will always be available through all modes when possible.
// RESULT_INCLUDE_CALLER_RETURNADDRESS
// This controls whether or not the _ReturnAddress() of the function that includes the macro will
// be reported to telemetry. Note that this is in addition to the _ReturnAddress() of the actual
// macro position (which is always reported). The values are:
// 0 - The address is not included
// 1 - The address is included
// The default value is '1'.
// RESULT_INLINE_ERROR_TESTS
// For conditional macros (other than RETURN_XXX), this controls whether branches will be evaluated
// within the call containing the macro or will be forced into the function called by the macros.
// Pushing branching into the called function reduces code size and the number of unique branches
// evaluated, but increases the instruction count executed per macro.
// 0 - Branching will not happen inline to the macros
// 1 - Branching is pushed into the calling function via __forceinline
// The default value is '1'. Note that XXX_MSG functions are always effectively mode '0' due to the
// compiler's unwillingness to inline var-arg functions.
// RESULT_DIAGNOSTICS_LEVEL_FAIL_FAST
// RESULT_INCLUDE_CALLER_RETURNADDRESS_FAIL_FAST
// RESULT_INLINE_ERROR_TESTS_FAIL_FAST
// These defines are identical to those above in form/function, but only applicable to fail fast error
// handling allowing a process to have different diagnostic information and performance characteristics
// for fail fast than for other error handling given the different reporting infrastructure (Watson
// vs Telemetry).
// Set the default diagnostic mode
// Note that RESULT_DEBUG_INFO and RESULT_SUPPRESS_DEBUG_INFO are older deprecated models of controlling mode

//! exception is thrown, rather than after that unknown exception has been unwound. Though less efficient, this leads
//! to a better debugging experience when analyzing unknown exceptions.
//!
//! For example:
//! ~~~~
//! hr = wil::ResultFromExceptionDebug(WI_DIAGNOSTICS_INFO, [&]
//! {
//! FunctionWhichMayThrow();
//! });
//! ~~~~
//! Assume FunctionWhichMayThrow() has a bug in it where it accidentally does a `throw E_INVALIDARG;`. This ends up
//! throwing a `long` as an exception object which is not what the caller intended. The normal @ref ResultFromException
//! would fail-fast when this is encountered, but it would do so AFTER FunctionWhichMayThrow() is already off of the
//! stack and has been unwound. Because SEH is used for ResultFromExceptionDebug, the fail-fast occurs with everything
//! leading up to and including the `throw INVALIDARG;` still on the stack (and easily debuggable).
//!
//! The penalty paid for using this, however, is efficiency. It's far less efficient as a general pattern than either
//! using ResultFromException directly or especially using try with CATCH_ macros directly. Still it's helpful to deploy
//! selectively to isolate issues a component may be having with unknown/unhandled exceptions.
//!
//! The ability to vary the SupportedExceptions that this routine provides adds the ability to track down unexpected
//! exceptions not falling into the supported category easily through fail-fast. For example, by not supporting any
//! exception, you can use this function to quickly add an exception guard that will fail-fast any exception at the point
//! the exception occurs (the throw) in a codepath where the origination of unknown exceptions need to be tracked down.
//!
//! This will fail-fast and stop on std::exception based exceptions (but not Platform::Exception^ or wil::ResultException).
//! Using this can help isolate where an unexpected exception is being generated from.
//! @param diagnostics Always pass WI_DIAGNOSTICS_INFO as the first parameter
//! @param supported What kind of exceptions you want to support
//! @param functor A lambda that accepts no parameters; any return value is ignored
