- Support for error objects crossing DLL boundaries on Windows via BOOST_LEAF_CFG_WIN32=2. - Internal TLS interface improvements, separating logical allocation from reading. - Dynamic allocations (if enabled) for on_error objects now happens before stack unwinding begins. - BOOST_LEAF_SYMBOL_VISIBLE declarations now separated in config/visibility.hpp.
Example Programs Using LEAF to Handle Errors
-
print_file: This directory contains several versions of a trivial program which takes a file name on the command line and prints it. Each version uses a different error handling implementation.
-
try_capture_all_result.cpp: Shows how to transport error objects between threads in a
leaf::result<T>object without using exception handling. -
try_capture_all_exceptions.cpp: Shows how to transport error objects between threads in a
leaf::result<T>object using exception handling. -
lua_callback_result.cpp: Transporting arbitrary error objects through an uncooperative C API.
-
lua_callback_exceptions.cpp: Transporting arbitrary error objects through an uncooperative API using exceptions.
-
exception_to_result.cpp: Demonstrates how to transport exceptions through a
noexceptlayer in the program. -
exception_error_log.cpp: Using
accumulateto produce an error log. -
exception_error_trace.cpp: Same as above, but the log is recorded in a
std::dequerather than just printed. -
print_half.cpp: This is a Boost Outcome example adapted to LEAF, demonstrating the use of
try_handle_someto handle some errors, forwarding any other error to the caller.
