I'm trying to add error handling to my code, sadly I'm having trouble getting it to work:
If your Rust function returns a Result object which contains an error, then a Lua error will be triggered.
My setup looks like this:
rust runtime -> calls into a lua script -> calls into a rust function I'm providing
the error happens inside the rust function that I'm calling. The script looks like this:
function verify(user, password)
return execve("./2docs/test.sh", {user, password}) == 0
end
where ./2docs doesn't exist and causes an Err(_), but the result of .call_with_args is Ok(LuaBoolean(false)). When removing the == 0 I'm getting LuaNil which doesn't seem like an error either.
What I'm trying to do:
either get an error inside the lua script that I can return to the runtime
do something inside the rust function that allows my to abort the script and return the error directly to the runtime
