missing_docs not triggered when missing docs on trait alias

[zopsicle]

I tried this code:

//! example
#![feature(trait_alias)]
#![warn(missing_docs)]
pub trait T = Send;

I expected to see this happen: “missing documentation for a trait alias” diagnostic

Instead, this happened: no diagnostic

Running the following code on the nightly:

#![feature(trait_alias)]
#![warn(missing_docs)]

pub trait T = Send;

gives the following output:

   Compiling playground v0.0.1 (/playground)
warning: missing documentation for the crate
 --> src/lib.rs:1:1
  |
1 | / #![feature(trait_alias)]
2 | | #![warn(missing_docs)]
3 | |
4 | | pub trait T = Send;
  | |___________________^
  |
note: the lint level is defined here
 --> src/lib.rs:2:9
  |
2 | #![warn(missing_docs)]
  |         ^^^^^^^^^^^^

So I guess the difference is the //! example ?

That diagnostic warns about missing docs on the crate, but not on the trait alias.

That diagnostic warns about missing docs on the crate, but not on the trait alias.

Ah yes, thanks

This is now fixed.
