# Description This PR allows the helper attribute `nu_value(rename = "...")` to be used on struct fields and enum variants. This allows renaming keys and variants just like [`#[serde(rename = "name")]`](https://serde.rs/field-attrs.html#rename). This has no singular variants for `IntoValue` or `FromValue`, both need to use the same (but I think this shouldn't be an issue for now). # User-Facing Changes Users of the derive macros `IntoValue` and `FromValue` may now use `#[nu_value(rename = "...")]` to rename single fields, but no already existing code will break.
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.
