Derive data struct for enum

This crate provides VariantsDataStruct derive macro that generates a struct for an enum, where each field corresponds to a variant of the enum. Each field's type is a struct representing the data of that variant or () if the variant has no data.

Example

use variants_data_struct::VariantsDataStruct;

#[derive(VariantsDataStruct)]

pub enum MyEnum {
    UnitEnum,
    TupleEnum(i32, String),
    StructEnum { id: u32, name: String },
}

// Equivalent to:
//
// pub struct MyEnumVariantsData {
//     pub unit_enum: (),
//     pub tuple_enum: TupleEnumVariantType,
//     pub struct_enum: StructEnumVariantType,
// }
// pub struct TupleEnumVariantType(pub i32, pub String);
//
// pub struct StructEnumVariantType {
//     pub id: u32,
//     pub name: String,
// }
