What it does

Checks for manual implementations of str::repeat

Why is this bad?

These are both harder to read, as well as less performant.

Example

let x: String = std::iter::repeat(\'x\').take(10).collect();

Use instead:

let x: String = "x".repeat(10);

Configuration

  • msrv: The minimum rust version that the project supports. Defaults to the rust-version field in Cargo.toml

    (default: current version)
