Structs§
- Boolean
Array - An array of boolean values
- Dictionary
Array - An array of dictionary encoded values
- Fixed
Size Binary Array - An array of fixed size binary arrays
- Fixed
Size List Array - An array of fixed length lists, similar to JSON arrays
(e.g.
["A", "B"]). - Generic
Byte Array - An array of variable length byte arrays
- Generic
Byte View Array - Variable-size Binary View Layout: An array of variable length bytes views.
- Generic
List Array - An array of variable length lists, similar to JSON arrays
(e.g.
["A", "B", "C"]). This struct specifically represents the list layout. Refer toGenericListViewArrayfor the list-view layout. - Generic
List View Array - An array of variable length lists, specifically in the list-view layout.
- MapArray
- An array of key-value maps
- Native
Adapter - An optional primitive value
- Null
Array - An array of null values
- Primitive
Array - An array of primitive values, of type

DictionaryArraywith the key type erased - Array
- An array in the arrow columnar format
- Array
Accessor - A generic trait for accessing the values of an
Array - Binary
Array Type - A trait for Arrow Binary Arrays, currently four types are supported:
- Offset
Size Trait - A type that can be used within a variable-size array to encode offset information
- String
Array Type - A trait for Arrow String Arrays, currently three types are supported:
Functions§
