# Description Adds a new `Filesize` type so that `FromValue` can be used to convert a `Value::Filesize` to a `Filesize`. Currently, to extract a filesize from a `Value` using `FromValue`, you have to extract an `i64` which coerces `Value::Int`, `Value::Duration`, and `Value::Filesize` to an `i64`. Having a separate type also allows us to enforce checked math to catch overflows. Similarly, it allows us to specify other trait implementations like `Display` in a common place. # User-Facing Changes Multiplication with filesizes now error on overflow. Should not be a breaking change for plugins (i.e., serialization) since `Filesize` is marked with `serde(transparent)`. # Tests + Formatting Updated some tests.
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.
