doc-comment
![](https://img.shields.io/badge/rust-documentation-blue.svg)
Write doc comments from macros.
Usage example
// Of course, we need to import the `doc_comment` macro:
#[macro_use]
extern crate doc_comment;
// If you want to test examples in your README file.
doctest!("../README.md");
// If you want to test your README file ONLY on "cargo test":
#[cfg(doctest)]
doctest!("../README.md");
// If you want to document an item:
doc_comment!(concat!("fooo", "or not foo"), pub struct Foo {});
