Any LLVM safe wrapper (or some light for writing one)?

I am currently trying to write language implementations with LLVM. Of course, I am doing it in rust. Is there any LLVM safe wrapper? I am trying to write my internal one, but it is kind of messy. I mean, I have no clue if things are allocated or deallocated with a function or whatever. Also, the LLVM documentation on C’s API is kind of poor.

use lazy_static::lazy_static;
use llvm_sys::{core::*, initialization::*, prelude::*};
use std::{ffi::CStr, marker::PhantomData, sync::Mutex};

#[derive(Debug)]
pub struct Session(());

#[derive(Debug)]
pub struct Module<'sess> {
    alloc: LLVMModuleRef,
    _marker: PhantomData<&'sess Session>,
}

#[derive(Debug)]
pub struct Ctxt<'sess> {
    alloc: LLVMContextRef,
    global: bool,
    _marker: PhantomData<&'sess Session>,
}

I found Inkwell few weeks ago.

Inkwell is probably the best interface to LLVM at the moment. I’ve used it in the past and even contributed a little to their JIT execution engine, and found it to be quite nice to work with.
