RS.CLIPPY.IMPLICIT_CLONE

Implicitly cloning a value by invoking a function on its dereferenced type

What it does

Checks for the usage of _.to_owned(), vec.to_vec(), or similar when calling _.clone() would be clearer.

Why is this bad?

These methods do the same thing as _.clone() but may be confusing as to why we are calling to_vec on something that is already a Vec or calling to_owned on something that is already owned.

Example

let a = vec![1, 2, 3];
let b = a.to_vec();
let c = a.to_owned();

Use instead:

let a = vec![1, 2, 3];
let b = a.clone();
let c = a.clone();
