Struct FixedSizeChunker 

pub struct FixedSizeChunker { /* private fields */ }

Splits text into fixed-size chunks by character count with configurable overlap.

Chunk IDs are generated as {document_id}_{chunk_index}. Each chunk inherits the parent document’s metadata plus a chunk_index field.

Example

use adk_rag::FixedSizeChunker;

let chunker = FixedSizeChunker::new(256, 50);
let chunks = chunker.chunk(&document);

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

Create a new FixedSizeChunker.

Arguments

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