Struct ChunkConfig 

pub struct ChunkConfig {
    pub max_chunk_bytes: usize,
    pub window_size: usize,
    pub window_overlap: usize,
}

Runtime configuration for the chunking pipeline.

All size values are in bytes. Pass to chunk_file to control chunk sizing without recompilation.

Fields

max_chunk_bytes: usize

Maximum chunk content length in bytes before splitting into windows. Chunks larger than this are split even if tree-sitter found them as a single definition (e.g., a 500-line function).

window_size: usize

Target window size in bytes for the sliding-window fallback chunker. ~2KB of source text ≈ 128-256 tokens after BPE, well within the 512-token model limit and optimal for embedding quality.

window_overlap: usize

Overlap between adjacent windows in bytes. Ensures definitions spanning a window boundary are captured in at least one window. Defaults to 25% of window_size.

Trait Implementations

Performs copy-assignment from source.

impl Debug for ChunkConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for ChunkConfig

fn default() -> Self

Returns the “default value” for a type.
