[−][src]Struct contrail::storage::NonBacktrackable
Objects stored on the trail in stable memory.
Instead of using NonBacktrackable
directly, it's often easier to use the type definitions
NonBacktrackableValue
and
NonBacktrackableArray
.
Examples
use contrail::{NonBacktrackableValue, TrailBuilder}; let mut builder = TrailBuilder::new(); let non_backtrackable_counter = NonBacktrackableValue::new(&mut builder, 0); let mut trail = builder.finish(); assert_eq!(non_backtrackable_counter.get(&trail), 0); trail.new_level(); non_backtrackable_counter.update(&mut trail, |x| x + 1); assert_eq!(non_backtrackable_counter.get(&trail), 1); trail.backtrack(); assert_eq!(non_backtrackable_counter.get(&trail), 1);
