Kind

Enum Kind 

Source
pub enum Kind {
    String = 0,
    Hash = 1,
    Set = 2,
    Zset = 3,
    List = 4,
    Stream = 5,
    Array = 6,
}
Expand description

What TYPE calls a key, and what the meta byte’s tag holds.

The numbers are the same numbers yo_format::ValueType uses on disk, so that saving a key is a copy of the tag rather than a translation of it. There is a test at the bottom of this file holding the two in step, and it takes a dev dependency on yo-format for no other reason.

The list is shorter than the on disk one because some of those are the same thing in memory. A bitmap is a string and a HyperLogLog is a string, in Redis as much as here, and TYPE on either answers string. The catalog draws finer lines because a reader wants to know what a blob meant.
