Function Documentation

◆ make_and_throw()

template<typename EXCEPTION , typename FUNC >

void make_and_throw ( FUNC func )

A convenience function for throwing exceptions. Lets you do this:

int x = computation() if (x != 0) { make_and_throw([&](auto&& s) { s << "x was not zero! it was " << x; }); }

Definition at line 66 of file Exception.h.

◆ make_from_stream()

template<typename T , typename FUNC >

auto make_from_stream ( FUNC func )

A convenience function for constructing things that expect strings, but when you would like to use a stream. Such as throwing exceptions. Lets you do this:

int x = computation() if (x != 0) { throw make_from_stream<std::logic_error>([&](auto&& s) { s << "x was not zero! it was " << x; }); }

Definition at line 85 of file Exception.h.

◆ printExceptionToOutAndErr()

void printExceptionToOutAndErr	(	std::exception_ptr	eptr,
		const char *	line_prefix,
		const char *	message
	)

inline

Prints a message to both stderr and stdout derived from eptr Intended to be used when an exception is going to be ignored. Handles std::nested_exception properly, and will print messages from the nested exceptions.

Definition at line 134 of file Exception.h.

◆ string_from_stream()

template<typename F >

std::string string_from_stream ( F && f )

Runs the given functor on a stringstream, and retuns the string

Definition at line 95 of file Exception.h.

◆ tryToSafelyPrintExceptionInfo()

void tryToSafelyPrintExceptionInfo	(	std::exception_ptr	eptr,
		std::ostream &	os,
		const char *	action_name
	)

inlinenoexcept

Print the given eptr to os, reasonably safely Intended for use in a destructor or something, when an throw exception cannot be tolerated. Does not handle std::nested_exception specially. Will not allocate, except if os does
