Addresses some null handling issues in #6882 # Description This changes the implementation of guessing a column type when a schema is not specified. New behavior: 1. Use the first non-Value::Nothing value type for the columns data type 2. If the value type changes (ignoring Value::Nothing) in subsequent values, the datatype will be changed to DataType::Object("Value", None) 3. If a column type does not have a value type, DataType::Object("Value", None) will be assumed.
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.
