Value Structs derive macros for Rust to support the newtype pattern

A very simple derive macros to support strong type system and the new type pattern (https://doc.rust-lang.org/1.0.0/style/features/types/newtype.html).

For example:

use rvs_derive::ValueStruct;

#[derive(ValueStruct)]
struct UserId(String);

let uid : UserId = "my-uid".into();

ValueStruct generates for you:

  • std::convert::From<> instances automatically to help you to create your structs.
  • an inline value() function to access your field directly without using .0.

There are different behaviour for different field types:

  • for std::string::String it generates additional instance for From<&str>
  • for scalar types value() the result type isn't a reference, for others it is.
