Struct TtlConfig 

pub struct TtlConfig {
    pub ttl: NonZeroU32,
    pub ttl_bits: BitCount,
}

Configuration for the TTL field.

Used to define memory used by the TTL field and the default value.

Examples

use cuckoo_clock::config::TtlConfig;

let ttl_config = TtlConfig {
    ttl: 100.try_into()?,
    ttl_bits: 7.try_into()?
};

Fields

ttl: NonZeroU32

The default TTL counter value for newly inserted items. The actual lifetime duration will be defined by this value combined with the frequency of calls to crate::CuckooFilter::scan_and_update_full. Each call to crate::CuckooFilter::scan_and_update_full will reduce the counter by 1, until it reaches 0, when the item is removed.

ttl_bits: BitCount

Number of bits used to represent the TTL counter. Larget bit counts allow higher TTL to be represented.

Trait Implementations

impl Clone for TtlConfig

fn clone(&self) -> TtlConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TtlConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for TtlConfig

impl PartialEq for TtlConfig

fn eq(&self, other: &TtlConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
