Struct RecursiveChunker 

pub struct RecursiveChunker { /* private fields */ }

Available on crate feature rag only.

Splits text hierarchically: paragraphs → sentences → words.

First splits by paragraph separators (\n\n). If a paragraph exceeds chunk_size, splits by sentence boundaries (. , ! , ? ). If a sentence still exceeds chunk_size, splits by word boundaries. Overlap is applied between chunks at each level.

Example

use adk_rag::RecursiveChunker;

let chunker = RecursiveChunker::new(512, 100);
let chunks = chunker.chunk(&document);

Implementations

impl RecursiveChunker

pub fn new(chunk_size: usize, chunk_overlap: usize) -> RecursiveChunker

Create a new RecursiveChunker.

Arguments

• chunk_size — maximum number of characters per chunk
• chunk_overlap — number of overlapping characters between consecutive chunks
