Reverts nushell/nushell#10943 The current implementation of `arr_to_value` is unsound, as it allows casts of arbitrary data to arbitrary types without being marked `unsafe`. The full safety requirements to perform both the cast and the following unchecked access are not as clear that a simple change of `fn arr_to_value` to `unsafe fn arr_to_value` could be blessed without further investigation. cc @ayax79
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.
