Module concat 

Defines concat kernel for ArrayRef

Example:

use arrow_array::{ArrayRef, StringArray};
use arrow_select::concat::concat;

let arr = concat(&[
    &StringArray::from(vec!["hello", "world"]),
    &StringArray::from(vec!["!"]),
]).unwrap();
assert_eq!(arr.len(), 3);

Functions

binary_capacity 🔒

concat

Concatenate multiple [Array] of the same type into a single [ArrayRef].

concat_batches

Concatenates batches together into a single [RecordBatch].

concat_boolean 🔒

concat_byte_view 🔒

concat_bytes 🔒

concat_dictionaries 🔒

concat_fallback 🔒

Concatenates arrays using MutableArrayData

concat_fixed_size_list 🔒

Concatenates the child values and the validity bitmaps, without the per-array ArrayData that concat_fallback builds: with many short arrays that is most of the cost.

concat_list_view 🔒

concat_lists 🔒

concat_maps 🔒

concat_primitives 🔒

concat_run_arrays 🔒

Concatenate multiple RunArray instances into a single RunArray.
