# Description These make it easy to make a Span that covers an entire argument and the span of all arguments in a Call. Call::arguments_span() is useful for errors where a command may accept arguments or the pipeline, but not both. Argument::span() is useful for errors where an arguments is incompatible with one or more other arguments. In particular, I wish to use this to create an error for an implementation of #9563 that either allows arguments to set limits: ```nushell limits set RLIMIT_NOFILE --soft 255 --hard 1024 ``` Or pipeline: ```nushell {name: RLIMIT_NOFILE, soft: 255} | limits set ``` But not both: ``` ❯ [{name: RLIMIT_NOFILE, soft: 255, hard: 1024}] | limits set AS --soft 5 --hard 5 Error: nu:🐚:incompatible_parameters × Incompatible parameters. ╭─[source:1:1] 1 │ [{name: RLIMIT_NOFILE, soft: 255, hard: 1024}] | limits set AS --soft 5 --hard 5 · ───────────────────────┬────────────────────── ──────────┬───────── · │ ╰── or arguments, not both · ╰── Supply either pipeline ╰──── ``` # User-Facing Changes Only nushell Command API changes |

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.
