Chunker class

Divides text streams into manageable chunks for processing.

The Chunker class is responsible for breaking down large text streams into smaller, consistently sized chunks that can be processed by language models or embedding systems. It ensures chunks are properly sized for model context windows and can create overlapping chunks to preserve context across chunk boundaries.

Constructors

Chunker.new({int chunkSize = 300})
Creates a new Chunker with the specified chunk size.
