forked from extern/nushell
# Description this pr adds the following commands to `std iter` - `iter find-index` -> returns the index of the first element that matches the predicate or `-1` if none - `iter flat-map` -> maps a closure to each nested structure and flattens the result - `iter zip-with` -> zips two structures and applies a closure to each of the zips it also fixes some \*\*very minor\*\* inconsistencies in the module
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.
