Struct ByteArrayInterner 

struct ByteArrayInterner {
    state: RandomState,
    map: HashTable<Entry>,
    page: Vec<u8>,
}

Fields

state: RandomState

map: HashTable<Entry>

Underlying hash set for each distinct value

page: Vec<u8>

Encoded dictionary page: each value prefixed by its length as a u32
