introspection

A rust introspection procedural macro.

What does it do?

It simply converts code from compile stage (from syn crate) to simplier structs. Works for structs and enums. You may obtain this information through a Introspection trait.

Usage

1. Add introspection as dependency in your Cargo.toml:

[dependencies]
introspection-derive = "0.1"
introspection = "0.1"

2. Create a struct or enum:

#[macro_use]
extern crate introspection_derive;
extern crate introspection;


#[derive(Introspection)]
struct FrenchToast {
    private_field: u64,
    pub public_field: u8,
}

3. Use it:

fn main() {
   use introspection::{ Introspection };
   println!("Introspection: {:?}", FrenchToast::introspection());
}

4. See the results:

      Running `target/debug/introspection-test`
Introspection: IntrospectionInfo { ident: "FrenchToast", visibility: Inherited, entity_type: Struct, fields: ["private_field", "public_field"] }

P.S. Personally I doubt this crate will help someone because it is impossible to do a lot of interesting and useful stuff from procedural macro at this moment unfortunately (rustc v1.15).
