Lint for 4 / (////) to help detect broken doc comments

[alice-i-cecile]

What it does

Detects four consecutive forward slash characters.

This is almost always indicative of a broken doc comment.

Lint Name

four-forward-slashes

Category

suspicious

Advantage

• The doc comment appears as expected.

Drawbacks

Users may have a non-standard style that uses 4 forward slashes semantically.

Example

//// The life total of a unit
struct Life(u8);

Was likely intended to be:

/// The life total of a unit
struct Life(u8);
