Struct memflow::types::cache::count_validator::CountCacheValidator
source · pub struct CountCacheValidator { /* private fields */ }
Expand description
Validator for limiting the cache time based on a time Instant
Remarks
This validator is only available when being compiled with std
.
When using no_std
you might want to use another validator.
TODO: add other validators here
Implementations§
source§impl CountCacheValidator
impl CountCacheValidator
sourcepub fn new(valid_count: usize) -> Self
pub fn new(valid_count: usize) -> Self
Creates a new CountCacheValidator with a customizable valid count.
Valid count is increased on every memory operation by the validator users.
Examples:
use memflow::types::cache::{CacheValidator, CountCacheValidator};
let mut validator = CountCacheValidator::new(100);
validator.allocate_slots(1);
assert!(!validator.is_slot_valid(0));
validator.validate_slot(0);
// For a hundred times the slot should stay valid
for _ in 0..100 {
assert!(validator.is_slot_valid(0));
validator.update_validity();
}
// At this point it should become invalid
assert!(!validator.is_slot_valid(0));
