# Description On 64-bit platforms the current size of `Value` is 56 bytes. The limiting variants were `Closure` and `Range`. Boxing the two reduces the size of Value to 48 bytes. This is the minimal size possible with our current 16-byte `Span` and any 24-byte `Vec` container which we use in several variants. (Note the extra full 8-bytes necessary for the discriminant or other smaller values due to the 8-byte alignment of `usize`) This is leads to a size reduction of ~15% for `Value` and should overall be beneficial as both `Range` and `Closure` are rarely used compared to the primitive types or even our general container types. # User-Facing Changes Less memory used, potential runtime benefits. (Too late in the evening to run the benchmarks myself right now)
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.
