How to store a Module object in a struct?

[sbourdeauducq]

The following code fails to compile:

struct Test<'ctx> {
    context: inkwell::context::Context,
    result: Result<inkwell::module::Module<'ctx>, String>,
}

impl<'ctx> Test<'ctx> {
    fn new() -> Self {
        Self {
            context: inkwell::context::Context::create(),
            result: Err("".to_string()),
        }
    }

    fn update(&mut self) {
        self.result = Ok(self.context.create_module("my_module"));
    }
}

fn main() {
    let mut x = Test::new();
    x.update();
}

With this error:

error: lifetime may not live long enough
  --> src/main.rs:15:26
   |
6  | impl<'ctx> Test<'ctx> {
   |      ---- lifetime `'ctx` defined here
...
14 |     fn update(&mut self) {
   |               - let's call the lifetime of this reference `'1`
15 |         self.result = Ok(self.context.create_module("my_module"));
   |                          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ argument requires that `'1` must outlive `'ctx`

How to fix the error and allow the storage of an inkwell Module in a struct?

Context would have to live outside of Test, then you can feed in things generated from it or even a reference to context &'ctx Context as a field
