Crate readme

Short description A deriving proc-macro for generating functions to automatically give access to the inner members of enum.

Long description The crate provides a proc-macro that allows users to derive access functions for the inner fields of enums. It supports single item enums, multiple unnamed fields, and named fields, with corresponding accessor methods, including unsafe variants for unchecked access.

Features • Derives access functions for inner members of enums • Supports both unnamed and named fields • Provides unsafe methods for direct access

Code Examples Basic unnamed field case

 use enum_as_inner::EnumAsInner;

#[derive(Debug, EnumAsInner)]
enum OneEnum {
    One(u32),
}

let one = OneEnum::One(1);

assert_eq!(*one.as_one().unwrap(), 1);
assert_eq!(one.into_one().unwrap(), 1);

Multiple, unnamed field case

 use enum_as_inner::EnumAsInner;

#[derive(Debug, EnumAsInner)]
enum ManyVariants {
    One(u32),
    Two(u32, i32),
    Three(bool, u32, i64),
}

let mut many = ManyVariants::Three(true, 1, 2);

assert_eq!(many.as_three().unwrap(), (&true, &1_u32, &2_i64));

Multiple, named field case

 use enum_as_inner::EnumAsInner;

#[derive(Debug, EnumAsInner)]
enum ManyVariants {
    One{ one: u32 },
    Two{ one: u32, two: i32 },
    Three{ one: bool, two: u32, three: i64 },
}

let mut many = ManyVariants::Three{ one: true, two: 1, three: 2 };

assert_eq!(many.as_three().unwrap(), (&true, &1_u32, &2_i64));
