[Feature Request] Loading external libraries about mlua HOT 6 CLOSED

I agree that this functionality could be useful and working on creating more generic implementation.

My idea is to provide a method to create Function from a raw C function (ffi::lua_CFunction type) and then it should be easy to add any required functionality.
For example, you could set package.preload[modname] to a C function and then Lua require would magically work.

Also I'm thinking to add load_from_function method similar to requiref/require.

I pushed a commit 1fe5830 to the dev branch with new functions: load_from_function and create_c_function. Could you check please that this provides a solution for your case?

Usage example:

let lsqlite3_open = unsafe { lua.create_c_function(luaopen_lsqlite3) }?;
let _: Value = lua.load_from_function("lsqlite3", lsqlite3_open)?;

from mlua.

Am I correct that you want to statically link libraries such as LuaSQlite3 to your application?

I would probably include some (or all, if necessary) of the libraries directly as source code, because some of them (e.g. lbc) are only available as such.

from mlua.

Yep, that does it. Thank you so much!

This is published now in v0.6.2
