What it does

Checks for the use of concat!("takes a single string literal").

Advantage

Redundant code. The type of a literal yielded by concat! and the type of a string literal are both &'static str.

Drawbacks

No response

Example

let foo = concat!("foo");

Could be written as:

let foo = "foo";
