Dead simple Rust quasi-quoting

Dead Simple Rust Quasi-Quoting

Quasi-quoting without a Syntex dependency, intended for use with Macros 1.1.

[dependencies]
quote = "0.2"

#[macro_use]
extern crate quote;

Interpolation is done with #var:

let tokens = quote! {
    struct SerializeWith #generics #where_clause {
        value: &'a #field_ty,
        phantom: ::std::marker::PhantomData<#item_ty>,
    }

    impl #generics serde::Serialize for SerializeWith #generics #where_clause {
        fn serialize<S>(&self, s: &mut S) -> Result<(), S::Error>
            where S: serde::Serializer
        {
            #path(self.value, s)
        }
    }

    SerializeWith {
        value: #value,
        phantom: ::std::marker::PhantomData::<#item_ty>,
    }
};

Repetition is done in one of three ways, similar to macro_rules! repetitions:

• #(var)* - no separators
• #(var),* - the character before the asterisk is used as a separator
• #(var;)* - the character before the close paren is used as a terminator
