Serde Type Name

Serde Type Name - lookup name of type for any struct or enum that derives serde Serialize. This is completely based on

Usage

extern crate serde_type_name;
extern crate serde;
#[macro_use]
extern crate serde_derive;

use serde::Serialize;
use serde_type_name::type_name;

#[derive(Serialize)]
enum SimpleEnum {
    A(i32),
    B,
    C { code: i32 },
}

#[derive(Serialize)]
struct SimpleStruct {
    pub a: i32,
}

#[derive(Serialize)]
struct GenericStruct<T: Serialize> {
    pub inner: T,
}

fn main() {
    assert_eq!("SimpleEnum", type_name(&SimpleEnum::A(10)).unwrap());
    assert_eq!("SimpleEnum", type_name(&SimpleEnum::B).unwrap());
    assert_eq!("SimpleEnum", type_name(&SimpleEnum::C { code: 32 }).unwrap());
    
    assert_eq!("SimpleStruct", type_name(&SimpleStruct { a: 20 }).unwrap());
    
    let gs = GenericStruct { inner: 32 };
    assert_eq!("GenericStruct", type_name(&gs).unwrap());
    
    let gs_enum = GenericStruct {
        inner: SimpleEnum::B,
    };
    assert_eq!("GenericStruct", type_name(&gs_enum).unwrap());
    assert_eq!("SimpleEnum", type_name(&gs_enum.inner).unwrap());
}
