Struct GlobalContextGuard

Source

pub struct GlobalContextGuard<C: 'static> { /* private fields */ }

Expand description

Guard returned by set_global_context.

When dropped, the previously installed context value (if any) is restored.

§Examples

use ad_tensors_rs::{set_global_context, with_global_context};

let _guard = set_global_context::<u32>(7);
let v = with_global_context::<u32, _>(|ctx| Ok(*ctx)).unwrap();
assert_eq!(v, 7);
