Trait Value 

pub trait Value: Parse + Clone {
    type Context: ContextLike;

    // Required method
    fn build(item: &Self, ctx: Ref<Self::Context>) -> Result<TokenStream>;

    // Provided method
    fn parse2(stream: TokenStream) -> Result<Self> { ... }
}

Required Associated Types

type Context: ContextLike

Required Methods
