A thread safe wrapper around lru::LruCache

Implementations

impl InMemoryCache

pub fn new(capacity: NonZeroUsize) -> Self

Creates a new LRU cache that holds at most cap items.

Trait Implementations

impl Cache for InMemoryCache

fn put(&self, key: &CacheKey, signed_packet: &SignedPacket)

Puts SignedPacket, if a version of the packet already exists, and it has the same SignedPacket::as_bytes, then only SignedPacket::last_seen will be updated, otherwise the input will be cloned.

fn capacity(&self) -> usize

Returns the maximum capacity of SignedPackets allowed in this cache.

fn len(&self) -> usize

Returns the number of SignedPackets in this cache.

fn get(&self, key: &CacheKey) -> Option<SignedPacket>

Reads SignedPacket from cache, while moving it to the head of the LRU list.

fn get_read_only(&self, key: &CacheKey) -> Option<SignedPacket>

Reads SignedPacket from cache, without changing the LRU list.

fn is_empty(&self) -> bool

Returns true if this cache is empty.

impl Clone for InMemoryCache

fn clone(&self) -> InMemoryCache

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InMemoryCache

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

Formats the value using the given formatter.
