Description

What it does

Checks whether a &str is wrapped in Path::new before being passed to a function that accepts impl AsRef<Path>. So somewhat similar to needless_borrow

Advantage
  • more concise
  • avoids the import
Drawbacks

can't think of any...

Example
std::fs::write(Path::new("foo.txt"), "foo");

Could be written as:

std::fs::write("foo.txt", "foo");

Research direction

The report names no files, tests, or entry points; start by reviewing the proposed behavior and its Path::new example. Done means the lint identifies unnecessary Path::new wrapping when a &str is accepted through impl AsRef, while preserving valid cases.
