Hi,

I did a proof of concept implementation of a HttpsFS. This FS allows to access over HTTPS. The whole implementation is work in progress and not ready for a pull. I use the pull request to announce this idea and hope i get some feedback. Would this be something, which you like to pull?

For a fix overview how the API works, see the https_fs_server.rs and https_fs.rs in the example directory,

I have a ToDo list, which can be found in src/impl/https.rs, but here are some higlights:

• Add user authentication
• Prepare the HttpsFS for WebAssembly
• Do a version check on session start (There are no sessions yet)
• Since this is a POC, the code is a mess. For example, all Errors are converted to VfsError::Other in the current implementation. This have to be fixed.

I noticed some oddities of the FileSystem trait:

• The exists() method is the only method, which does not return a VfsResult. This is a problem for the HttpsFS, since the connection to the HttpsFSServer may fail. In this case, it is not clear, whether a file exist or not. Therefor i would prefer to return an VfsError instead of a boolean.
• u64 is used for position in Files, but the traits std::io::Read and std::io::Write use usize for positions. (std::io::Seek uses u64 too, but this also is strange)

What is your opinion to all this?

Kind regards,

PS: I'm new to Rust and this is my first "project" after "Hello World!". There is probably a lot stuff, which can be improved.
