ca2abaf366 Auto merge of #5109 - phansch:ciao_util_dev, r=flip1995
Deprecate util/dev in favor of cargo alias

This means one less shell script and a bit more cross-platform support
for contributors.

If you've been using `./util/dev` before, this now becomes `cargo dev`.

The key part of this change is found in `.cargo/config` where an alias for calling the `clippy_dev` binary is defined.

changelog: none

New lint: pats_with_wild_match_arm

Wildcard use with other pattern in same match arm.

The wildcard covers other(s) pattern(s) as it will match anyway.

changelog: add new lint when multiple patterns (including wildcard) are used in a match arm.

f5d0a452ba Add lint for pub fns returning a Result without documenting errors
The Rust Book recommends that functions that return a `Result` type have
a doc comment with an `# Errors` section describing the kind of errors
that can be returned
(https://doc.rust-lang.org/book/ch14-02-publishing-to-crates-io.html#commonly-used-sections).
This change adds a lint to enforce this. The lint is allow by default;
it can be enabled with `#![warn(clippy::missing_errors_doc)]`.

Closes #4854.

Move use_self to nursery
Closes #4859

We have a lot of false positives in this lint, so I think it makes sense
to move this to the nursery until they are resolved.

changelog: Move `use_self` lint to nursery, due to many false positives
