Enum ChunkSizing 

pub enum ChunkSizing {
    Characters,
}

How chunk size is measured.

Defaults to Characters (Unicode character count). When using token-based sizing, chunks are sized by token count according to the specified tokenizer.

Token-based sizing uses HuggingFace tokenizers loaded at runtime, or a tokenizer backend you register yourself. Any tokenizer available on HuggingFace Hub can be used, including OpenAI-compatible tokenizers (e.g., Xenova/gpt-4o, Xenova/cl100k_base). To size chunks with your own tokenizer instead (llama.cpp/GGUF vocabularies, SentencePiece models, custom vocabs), register a TokenizerBackend with register_tokenizer_backend and set model to the registered name.

Variants

Characters

Size measured in Unicode characters (default).
