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:

#[derive(GetDerive)]
struct ToBeDerived {
    #[init(init_val)]
    val: OnceCell<String>,
}

fn init_val() -> String {
    "Some value".to_string()
}

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.
