doc-comment

Write doc comments from macros.

For now, please keep using version 0.3.* as the 0.4 is incomplete and is waiting for https://github.com/rust-lang/rust/issues/47809 to get stabilized.

Usage example

extern crate doc_comment;

// If you want to test examples in your README file.
doc_comment::doctest!("../README.md");
// If you want to "name" your tests.
doc_comment::doctest!("../README.md", readme);

// If you want to test your README file ONLY on "cargo test":
#[cfg(doctest)]
doc_comment::doctest!("../README.md");

// If you want to document an item:
#[doc_comment::doc_comment("fooo", "or not foo")]
pub struct Foo {
    #[doc_comment("a field!")]
    field: i32,
}

proc-macro

From the version 0.4, this crate will use proc-macro instead of macros, meaning that the minimum rust version will also greatly increase. If you don't want the proc-macro then use the 0.3.* versions!

For more information, take a look at the documentation.
