libc-system
libc-system provides a single cross‑platform function, [system], to execute a shell
command and return its exit code.
Overview
- On non‑Windows systems, it calls the C library’s
system()function. The command is passed as a narrow (UTF‑8) null‑terminated C string. - On Windows, it calls the C runtime’s
_wsystem()function. The command is converted from UTF‑8 to a wide (UTF‑16) string to properly handle non‑ASCII characters.
This crate lets you execute shell commands without having to worry about platform-specific differences.
Example
use system;
let exit_code = system;
println!;
Platform-specific details
- Windows: Uses
_wsystemfrom the C runtime. The command is converted into a wide (UTF‑16) string. - Others: Uses
systemfrom libc. The command is converted into a narrow, null‑terminated string.
