Apache DataFusion is an extensible query execution framework, written in Rust, that uses Apache Arrow as its in-memory format.

This crate contains functions for working with arrays, maps and structs, such as array_append that work with ListArray, LargeListArray and FixedListArray types from the arrow crate.

Most projects should use the datafusion crate directly, which re-exports this module. If you are already using the datafusion crate, there is no reason to use this crate directly in your project as well.
