search_trail
search_trail provides a data structure to manage values of primitive types. It means that you're able to
- create a new managed resource (of type
usize
,isize
,f32
, etc.) - Save the state of the manager (i.e. a "snapshot" of all the values of the managed resources)
- Restore the manager to its previous state (i.e. set the values of the managed resources to the previous snapshot)
The code was originally developped by @xgillard on maxi-cp-rs. This repo only adds the support for other type.
Example
use search_trail::{StateManager, SaveAndRestore, UsizeManager};
fn main() {
let mut mgr = StateManager::default();
let n = mgr.manage_usize(0);
assert_eq!(0, mgr.get_usize(n));
mgr.save_state();
mgr.set_usize(n, 20);
assert_eq!(20, mgr.get_usize(n));
mgr.save_state();
mgr.set_usize(n, 42);
assert_eq!(42, mgr.get_usize(n));
mgr.restore_state();
assert_eq!(20, mgr.get_usize(n));
mgr.restore_state();
assert_eq!(0, mgr.get_usize(n));
}
