Implementations

impl MemTable

pub fn get<K: AsRef<[u8]>>(&self, key: K, seqno: Option<SeqNo>) -> Option<Value>

Returns the item by key if it exists

The item with the highest seqno will be returned, if seqno is None

pub fn size(&self) -> u32

Get approximate size of memtable in bytes

pub fn len(&self) -> usize

Count the amount of items in the memtable

pub fn is_empty(&self) -> bool

Returns true if the memtable is empty

pub fn insert(&self, item: Value) -> (u32, u32)

Inserts an item into the memtable

pub fn get_lsn(&self) -> Option<SeqNo>

Returns the highest sequence number in the memtable
