Derive Macro DecodeScalar 

#[derive(DecodeScalar)]
{
    // Attributes available to this derive:
    #[knuffel]
}

Currently DecodeScalar derive is only implemented for enums

Enums

Only enums that contain no data are supported:

#[derive(knuffel::DecodeScalar)]
enum Color {
    Red,
    Blue,
    Green,
    InfraRed,
}

This will match scalar values in kebab-case. For example, this node decoder:

#[derive(knuffel::Decode)]
struct Document {
    #[knuffel(child, unwrap(arguments))]
    all_colors: Vec<Color>,
}

Can be populated from the following text:

all-colors "red" "blue" "green" "infra-red"
