ClosureGuard

xet_runtime::utils

Struct ClosureGuard 

Source 
pub struct ClosureGuard<F: FnOnce()> { /* private fields */ }
Expand description

Guard that executes a closure when dropped.

Useful for ensuring cleanup logic runs even on early returns or panics.

§Examples

use xet_runtime::utils::ClosureGuard;

let _guard = ClosureGuard::new(|| {
    println!("cleanup!");
});
// closure runs when _guard is dropped
