typename

A compatible, safe and stable alternative to Rust's std::intrinsics::type_name intrinsic.

DEPRECATION NOTICE: This crate has been deprecated. The type_name intrinsic has been stablized in Rust 1.38. Users of this crate are asked to migrate to std::any::type_name.

Example

extern crate typename;

use typename::TypeName;

fn main() {
    assert_eq!(String::type_name(), "std::string::String");
    assert_eq!(Vec::<i32>::type_name(), "std::vec::Vec<i32>");
    assert_eq!([0, 1, 2].type_name_of(), "[i32; 3]");
}
