# Description This adds support for reading and writing binary types in the polars commands. The `BinaryOffset` type can be read into a Nushell native `Value` type no problem, but unfortunately this is a lossy conversion, as there's no Nushell-native semantic equivalent to the fixed size binary type in Arrow. # User-Facing Changes `polars open` and `polars save` now work with binary types.
Nushell core libraries and plugins
These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.
Foundational libraries are split into two kinds of crates:
- Core crates - those crates that work together to build the Nushell language engine
- Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.
Plugins are likewise also split into two types:
- Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
- Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
