# Description This shrinks `Record`'s size in half and and allows you to include it in `Value` without growing the size. Changing the `Record` internals may have slightly different performance characteristics as the cache locality changes on lookups (if you directly need the value, it should be closer, but in other cases may blow up the cache line budget) Also different perf characteristics on creation expected. `Record::from_raw_cols_vals` now probably worse. ## Benchmarking Comparison with the main branch (boxed Record) revealed no significant change to the creation but an improvement when accessing larger N. The fact that this was more pronounced for nested access (still cloning before nushell/nushell#12325) leads to the conclusion that this may still be dominated by the smaller clone necessary for a 24-byte `Record` over the previous 48 bytes. # User-Facing Changes Reduced memory usage
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.
