cell_derive

A derive macro for quickly implementing get_or_init and get_mut functions for structs that contain OnceCell or OnceLock structs.

Usage

To use the macro on a struct, you need to define an initialization function somewhere and specify it with the init attribute.

For example:

```rust

[derive(GetDerive)]

struct ToBeDerived { #[init(init_val)] val: OnceCell, }

fn initval() -> String { "Some value".tostring() } ```

You can get the value of the field by calling the val() function that is generated.

Planned features:

• [ ] Generate functions for get_mut.
• [ ] Add support for OnceLock.
• [ ] Add support for renaming the generated functions.
