Lightweight declarative macro for sets of strings.

strum_lite::strum! {
    pub enum Casing {
        Kebab = "kebab-case",
        ScreamingSnake = "SCREAMING_SNAKE",
    }
}

Features

• Implements FromStr and Display.
• Attributes (docs, #[derive(..)]s) are passed through to the definition and variants.
• Aliases are supported.
• Custom enum discriminants are passed through.
• Generated code is #![no_std].
• The generated FromStr::Err provides a helpful error message.
• You may ask for a custom error type rather than using this crate's ParseError.

strum_lite::with_error! {
    #[derive(Default)]
    #[repr(u8)]
    pub enum Casing {
        Kebab = "kebab-case" | "kebab" = 1,
        #[default]
        ScreamingSnake = "SCREAMING_SNAKE" = 1 + 2,
    }
    throws
    #[derive(Clone, Copy)]
    ParseCasingError;
}
