nu_plugin_roaring

nu_plugin_roaring is a plugin for the Nushell that provides efficient bitmap operations using the Roaring Bitmap data structure.

Installation

cargo install nu_plugin_roaring
plugin add ~/.cargo/bin/nu_plugin_roaring
plugin use roaring

The plugin supports the following methods: new, len, list, contains, and serialize. Here are some examples:

Create a new bitmap, serialize it, and save it to a file:

[1..5 11..<15 21] | roaring new | roaring ser | save test.rr

Import a serialized bitmap and get its length:
```
open test.rr | roaring len
```
Import a serialized bitmap and check if it contains certain values:
```
open test.rr | roaring contains 1..3
```

Import a serialized bitmap and list certain values:

# List elements in the range from 1 to 15
open test.rr | roaring list 1..15
# List all elements
open test.rr | roaring list
