# Description Adds support for the following operations on plugin custom values, in addition to `to_base_value` which was already present: - `follow_path_int()` - `follow_path_string()` - `partial_cmp()` - `operation()` - `Drop` (notification, if opted into with `CustomValue::notify_plugin_on_drop`) There are additionally customizable methods within the `Plugin` and `StreamingPlugin` traits for implementing these functions in a way that requires access to the plugin state, as a registered handle model such as might be used in a dataframes plugin would. `Value::append` was also changed to handle custom values correctly. # User-Facing Changes - Signature of `CustomValue::follow_path_string` and `CustomValue::follow_path_int` changed to give access to the span of the custom value itself, useful for some errors. - Plugins using custom values have to be recompiled because the engine will try to do custom value operations that aren't supported - Plugins can do more things 🎉 # Tests + Formatting Tests were added for all of the new custom values functionality. - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - 🟢 `toolkit test` - 🟢 `toolkit test stdlib` # After Submitting - [ ] Document protocol reference `CustomValueOp` variants: - [ ] `FollowPathInt` - [ ] `FollowPathString` - [ ] `PartialCmp` - [ ] `Operation` - [ ] `Dropped` - [ ] Document `notify_on_drop` optional field in `PluginCustomValue` |

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.
