The concrete array definitions
Structs
Array of bools
A dictionary array where each element is a single value indexed by an integer key.
This is mostly used to represent strings or a limited set of primitive types as integers,
for example when doing NLP analysis or representing chromosomes by name.
An array where each element is a fixed-size sequence of bytes.
A list array where each element is a fixed-size sequence of values with the same
type whose maximum length is represented by a i32.
Generic struct for variable-size byte arrays
Generic struct for a variable-size list array.
A nested array type where each record is a key-value map.
Keys should always be non-null, but values can be null.
This struct is used as an adapter when creating
PrimitiveArray from an iterator.
FromIterator for PrimitiveArray takes an iterator where the elements can be into
this struct. So once implementing From or Into trait for a type, an iterator of
the type can be collected to PrimitiveArray.An Array where all elements are nulls
Array whose elements are of primitive types.
A nested array type where each child (called field) is represented by a separate
array.
A strongly-typed wrapper around a
DictionaryArray that implements ArrayAccessor
allowing fast access to its elementsAn Array that can represent slots of varying types.
Traits
Trait for dealing with different types of array at runtime when the type of the
array is not known in advance.
A generic trait for accessing the values of an
ArrayTrait bridging the dynamic-typed nature of Arrow (via
DataType) with the
static-typed nature of rust types (ArrowNativeType) for all types that implement ArrowNativeType.trait declaring an offset size, relevant for i32 vs i64 array types.
Functions
Constructs an array using the input
data.
Returns a reference-counted Array instance.Creates a new empty array

data_type of length length filled
entirely of NULL valuesType Definitions
A reference-counted reference to a generic
Array.An array where each element contains 0 or more bytes.

type whose memory offsets between elements are represented by a i64.
