Structs§

ArrowBytesMap
Optimized map for storing Arrow “bytes” types (String, LargeString, Binary, and LargeBinary) values that can produce the set of keys on output as GenericBinaryArray without copies.
ArrowBytesSet
HashSet optimized for storing string or binary values that can produce that the final set as a GenericStringArray with minimal copies.

Enums§

OutputType
Should the output be a String or Binary?
