Struct rustix::path::DecInt

source ·
pub struct DecInt { /* private fields */ }
Expand description

Format an integer into a decimal Path component, without constructing a temporary PathBuf or String.

This is used for opening paths such as /proc/self/fd/<fd> on Linux.

§Examples

use rustix::path::DecInt;

assert_eq!(
    format!("hello {}", DecInt::new(9876).as_ref().display()),
    "hello 9876"
);
