Enum Key 

pub enum Key {
    Account(Account),
    Int(i64),
    Principal(Principal),
    Subaccount(Subaccount),
    Timestamp(Timestamp),
    Uint(u64),

Key

Treating IndexKey as the atomic, normalized unit of the keyspace Backing primary keys and secondary indexes with the same value representation Planning to enforce Copy semantics (i.e., fast, clean, safe)

Variants

Account(Account)

Int(i64)

Principal(Principal)

Subaccount(Subaccount)

Timestamp(Timestamp)

Uint(u64)

Ulid(Ulid)
