//! Procedural macros to derive numeric traits in Rust.
//!
//! ## Usage
//!
//! Add this to your `Cargo.toml`:
//!
//! ```toml
//! [dependencies]
//! num-traits = "0.2"
//! num-derive = "0.3"
//! ```
//!
//! Then you can derive traits on your own types:
//!
//! ```rust
//! #[macro_use]
//! extern crate num_derive;
//!
//! #[derive(FromPrimitive, ToPrimitive)]
//! enum Color {
//! Red,
//! Blue,
//! Green,
//! }
//! # fn main() {}
//! ```
//!
//! ## Explicit import
//!
//! By default the `num_derive` procedural macros assume that the
//! `num_traits` crate is a direct dependency. If `num_traits` is instead
//! a transitive dependency, the `num_traits` helper attribute can be
//! used to tell `num_derive` to use a specific identifier for its imports.
//!
//! ```rust
//! #[macro_use]
//! extern crate num_derive;
//! // Lets pretend this is a transitive dependency from another crate
//! // reexported as `some_other_ident`.
//! extern crate num_traits as some_other_ident;
//!
//! #[derive(FromPrimitive, ToPrimitive)]
//! #[num_traits = "some_other_ident"]
//! enum Color {
//! Red,
//! Blue,
//! Green,
//! }
//! # fn main() {}
//! ```
extern crate proc_macro;
use proc_macro::TokenStream;
use proc_macro2::{Span, TokenStream as TokenStream2};
use quote::quote;
use syn::{Data, Fields, Ident};
/// Try to parse the tokens, or else return a compilation error
macro_rules! parse {
($tokens:ident as $type:ty) => {

Ok(parsed) => parsed,
Err(error) => {
return TokenStream::from(error.to_compile_error());
}
}
};
}
// Within `exp`, you can bring things into scope with `extern crate`.
//
// We don't want to assume that `num_traits::` is in scope - the user may have imported it under a
// different name, or may have imported it in a non-toplevel module (common when putting impls
// behind a feature gate).
//
// Solution: let's just generate `extern crate num_traits as _num_traits` and then refer to
// `_num_traits` in the derived code. However, macros are not allowed to produce `extern crate`
// statements at the toplevel.
//
// Solution: let's generate `mod _impl_foo` and import num_traits within that. However, now we
// lose access to private members of the surrounding module. This is a problem if, for example,
// we're deriving for a newtype, where the inner type is defined in the same module, but not
// exported.
//
// Solution: use the dummy const trick. For some reason, `extern crate` statements are allowed
// here, but everything from the surrounding module is in scope. This trick is taken from serde.
