# Description This changes the serialization of custom values within the plugin protocol to use MessagePack instead of bincode, removing the dependency on bincode entirely. Bincode does not seem to be very maintained anymore, and the externally tagged enum representation doesn't seem to always work now even though it should. Since we use MessagePack already anyway for the plugin protocol, this seems like an obvious choice. This uses the unnamed variant of the serialization rather than the named variant, which is what the plugin protocol in general uses. The unnamed variant does not include field names, which aren't really required here, so this should give us something that's more or less as efficient as bincode is. Should fix #13743. # User-Facing Changes - Will need to recompile plugins (but always do anyway) - Doesn't technically break the plugin protocol (custom value data is a black box / plugin implementation specific), but breaks compatibility between `nu-plugin-engine` and `nu-plugin` so they do need to both be updated to match. # Tests + Formatting All tests pass. # After Submitting - [ ] release notes
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.
