   • Add const fn as_str() method to the kind type, returning the variant name as &'static str. The value respects the display and rename attributes, so it always matches the Display output.

   Kinded is a Rust procedural macro that generates a companion "kind" enum with the same variants as your original enum but without the associated data.

   What is kinded?

   Kinded is a Rust procedural macro that generates a companion "kind" enum with the same variants as your original enum but without the associated data.

   New Features

   skip_derive attribute

   Opt out of default trait implementations when you need custom behavior or want to avoid conflicts with other derives.

   use kinded::Kinded;
   
   #[derive(Kinded)]
   #[kinded(skip_derive(Display, FromStr))]
   enum Status {
       Active,
       Inactive,
   }
   
   // Now you can implement Display and FromStr manually

   Available traits to skip: Display, FromStr, From, Clone, Copy, Debug, PartialEq, Eq.

   attrs attribute for generated enum

   Pass extra attributes to the generated kind enum, useful for integrating with serde and other derive macros.

   use kinded::Kinded;
   use serde::{Serialize, Deserialize};
   
   #[derive(Kinded)]
   #[kinded(attrs(derive(Serialize, Deserialize), serde(rename_all = "snake_case")))]
   enum Beverage {
       Coffee(String),
       Tea { flavor: String },
       Water,
   }
   
   // BeverageKind now has Serialize/Deserialize with snake_case naming

   Per-variant attrs attribute

   Apply attributes to individual kind variants for fine-grained control.

   use kinded::Kinded;
   use serde::{Serialize, Deserialize};
   
   #[derive(Kinded)]
   #[kinded(attrs(derive(Serialize, Deserialize)))]
   enum Priority {
       #[kinded(attrs(serde(rename = "p0")))]
       Critical,
       #[kinded(attrs(serde(rename = "p1")))]
       High,
       Normal,
       Low,
   }

   const fn kind() method

   The kind() method is now const fn, enabling use in const contexts.

   use kinded::Kinded;
   
   #[derive(Kinded)]
   enum Direction {
       North,
       South,
       East,
       West,
   }
   
   const NORTH_KIND: DirectionKind = Direction::North.kind();
   
   const fn is_vertical(dir: &Direction) -> bool {
       matches!(dir.kind(), DirectionKind::North | DirectionKind::South)
   }
