Description
What it does
Warn when a Debug
representation of Path
is used in format!
or println!
, instead of path.display()
.
Advantage
Rust doesn't guarantee how Debug
formatting looks like, and it could change in the future. For printing paths there's the dedicated .display()
method.
Drawbacks
Not every Debug
print of a Path
is incorrect: it may be used in dbg!()
, or when a PathBuf
is a field in a struct that is Debug
-printed as a whole.
Example
let path = Path::new("…");
println!("The path is {:?}", path);
Could be written as:
let path = Path::new("…");
println!("The path is {}", path.display());
