Example Programs Using LEAF to Handle Errors

• print_file: The complete example from the Five Minute Introduction. This directory contains several versions of the same program, each using a different error handling style.

• capture_in_result.cpp: Shows how to transport error objects between threads in a leaf::result<T> object.

• capture_in_exception.cpp: Shows how to transport error objects between threads in an exception object.

• lua_callback_result.cpp: Transporting arbitrary error objects through an uncooperative C API.

• lua_callback_eh.cpp: Transporting arbitrary error objects through an uncooperative exception-safe API.

• exception_to_result.cpp: Demonstrates how to transport exceptions through a noexcept layer in the program.

• exception_error_log.cpp: Using accumulate to produce an error log.

• exception_error_trace.cpp: Same as above, but the log is recorded in a std::deque rather than just printed.

• print_half.cpp: This is a Boost Outcome example adapted to LEAF, demonstrating the use of try_handle_some to handle some errors, forwarding any other error to the caller.

• asio_beast_leaf_rpc.cpp: A simple RPC calculator implemented with Beast+ASIO+LEAF.
