Troubles with replacing boost::iostreams::mapped_file_source due to non-copy attribute #70

Closed BullyWiiPlaza closed 3 years ago

So, I was about to replace Boost in my project and since I'm using boost::iostreams::mapped_file_source I stumpled across mio. Sadly, the non-copyable nature of mio causes plenty of hard to find compilation errors regarding object copying. Is that restriction really necessary? Boost gets along without this restriction just fine.

Would you suggest using std::move() everywhere or maybe wrapping mio::mmap_source into a std::shared_ptr when migrating?

Sorry, it looks like I didn't read the README carefully enough. 👍

You can do this via mio::shared_mmap_source.
