The concrete array definitions
Re-exports§
pub use crate::types::ArrowPrimitiveType;
Modules§
- Contains the
NullArraytype.
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::GenericListArrayas 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
DictionaryArraytyped on its child values array - A
RunArraytyped typed on its child values array - An array of values of varying types
Traits§
- A
DictionaryArraywith 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
- A trait for Arrow String Arrays, currently three types are supported:
Functions§
- get_
offsets 🔒 ⚠Helper function that gets offset from anArrayData - Constructs an array using the input
data. Returns a reference-countedArrayinstance. - Creates a new empty array
- Creates a new array of
data_typeof lengthlengthfilled entirely ofNULLvalues - Helper function for printing potentially long arrays.
