How to handle Results in the Rust/Lua boundary?

[nitnelave]

I'd like to have a lua function return a Result<T, String> (or something to that effect), and be able to understand when a function returns a Result<T, String>. On the Lua side, it should match the convention of returning the error as a second value, non-nil when there is an error.

The std::result::Result type implements IntoLuaMulti but doesn't seem to implement FromLuaMulti. Is that intentional or just hasn't been implemented yet?

I manage to work around that by using my own struct MyLuaResult<T>(Result<T, String>); but it feels like it should be provided by the crate: https://github.com/nitnelave/lldap_plugin_poc/blob/a84a9678713db21ed244f580818f090545d2449c/src/main.rs

Not intentionaly, I'll implement it!
