}
Expand description
Creates a record batch from literal slice of values, suitable for rapid testing and development.
Example:
use arrow_array::record_batch;
use arrow_schema;
let batch = record_batch!(
("a", Int32, [1, 2, 3]),
("b", Float64, [Some(4.0), None, Some(5.0)]),
("c", Utf8, ["alpha", "beta", "gamma"])
);
Due to limitation of create_array!
macro, support for limited data types is available.
