Crate nullable_struct

This crate provides a derive macro that makes it easy to create nullable versions of structs.

The Nullable derive macro wraps each field of a struct in an Option<T> type, allowing any field to be set to None.

It also generates helper methods for getting, setting, and initializing these optional fields.

Example

use your_crate_name::Nullable;

#[derive(Nullable)]
struct MyStruct {
    field1: i32,
    field2: String,
}

let s = NullableTestStruct::new(42, "hello".to_string());
assert_eq!(s.field1(), 42);
assert_eq!(s.field2(), "hello".to_string());

assert_eq!(instance.field1(), 42);
assert_eq!(instance.field2(), "Hello, World!".to_string());

Derive Macros

Nullable

Derive macro to make a struct “nullable” by wrapping all of its fields in Option<T> and generating convenient getter and setter methods for these fields.
