Implementations

impl CacheEntry

pub fn new(coords: TreeCoordinate, current_time_ms: u64, ttl_ms: u64) -> Self

Create a new cache entry.

pub fn coords(&self) -> &TreeCoordinate

Get the cached coordinates.

pub fn created_at(&self) -> u64

Get the creation timestamp.

pub fn last_used(&self) -> u64

Get the last used timestamp.

pub fn expires_at(&self) -> u64

Get the expiry timestamp.

pub fn path_mtu(&self) -> Option<u16>

Get the path MTU discovered during lookup, if available.

pub fn set_path_mtu(&mut self, mtu: u16)

Set the path MTU discovered during lookup.

pub fn is_expired(&self, current_time_ms: u64) -> bool

Check if this entry has expired.

pub fn touch(&mut self, current_time_ms: u64)

Touch the entry to update last_used time.

pub fn refresh(&mut self, current_time_ms: u64, ttl_ms: u64)

pub fn update( &mut self, coords: TreeCoordinate, current_time_ms: u64, ttl_ms: u64, )

Update the coordinates and refresh timestamps.

pub fn idle_time(&self, current_time_ms: u64) -> u64

Time since last use (for LRU eviction).

pub fn age(&self, current_time_ms: u64) -> u64

Age of the entry.

pub fn time_to_expiry(&self, current_time_ms: u64) -> u64

Time until expiry (0 if already expired).
