Arrow2

Arrow2 is a Rust library that implements data structures and functionality enabling interoperability with the arrow format.

The typical use-case for this library is to perform CPU and memory-intensive analytics in a format that supports heterogeneous data structures, null values, and IPC and FFI interfaces across languages.

Arrow2 is divided in 5 main APIs:

• a low-level API to efficiently operate with contiguous memory regions
• a high-level API to operate with arrow arrays
• a metadata API to declare and operate with logical types and metadata
• a compute API with operators to operate over arrays
• an IO API with interfaces to read from, and write to, other formats
