# Description
Introduces `polars into-schema` which allows converting Values such as
records to a schema. This implicitly happens when when passing records
into commands like `polars into-df` today. This allows you to convert to
a schema object ahead of time and reuse the schema object. This can be
useful for guaranteeing your schema object is correct.
```nu
> ❯ : let schema = ({name: str, type: str} | polars into-schema)
> ❯ : ls | select name type | polars into-lazy -s $schema | polars schema
╭──────┬─────╮

# User-Facing Changes
- Introduces `polars into-schema` allowing records to be converted to
schema objects.
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.
