CwdGuard

Struct CwdGuard 

Source
pub struct CwdGuard { /* private fields */ }
Expand description

Guard that temporarily changes the current working directory and restores the previous one on drop.

This guard is useful for testing or temporarily changing the working directory in a controlled manner. When the guard is dropped, it automatically restores the previous working directory.

§Error Handling

If restoring the previous directory fails during drop, the error is silently ignored (logged via let _ = ...). This is intentional to avoid panicking in destructors.

§Examples

use std::path::Path;

use xet_runtime::utils::CwdGuard;

// Temporarily change to a different directory
let new_dir = Path::new("/tmp");
let _guard = CwdGuard::set(new_dir)?;
// Current working directory is changed here
// When _guard is dropped, the previous directory is restored
