Structs§
- An array of boolean values
- An array of dictionary encoded values
- An array of fixed size binary arrays
- An array of [fixed length lists], similar to JSON arrays (e.g.
["A", "B"]
). - An array of variable length byte arrays
- Variable-size Binary View Layout: An array of variable length bytes views.
- An array of variable length lists, similar to JSON arrays (e.g.
["A", "B", "C"]
). - Different from
crate::GenericListArray
as it stores both an offset and length meaning that take / filter operations can be implemented without copying the underlying data. - An array of key-value maps
- An optional primitive value
- An array of null values
- An array of primitive values, of type
ArrowPrimitiveType
- An array of run-end encoded values
- An array of structs
- A
DictionaryArray
typed on its child values array - A
RunArray
typed typed on its child values array - An array of values of varying types
Traits§
- A
DictionaryArray
with the key type erased - An array in the arrow columnar format
- A generic trait for accessing the values of an
Array
- A type that can be used within a variable-size array to encode offset information
Functions§
- get_
offsets π βHelper function that gets offset from an [ArrayData
] - Constructs an array using the input
data
. Returns a reference-countedArray
instance. - Creates a new empty array
- Creates a new array of
data_type
of lengthlength
filled entirely ofNULL
values - print_
long_ πarray Helper function for printing potentially long arrays.
