Usage

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
