Struct HtmlHeaderTextSplitter 

pub struct HtmlHeaderTextSplitter { /* private fields */ }

Splits HTML content by header tags (h1, h2, h3, etc.).

Each section between headers becomes a separate document/chunk. Header text is added as metadata on the resulting chunks.

pub fn new(headers_to_split_on: Vec<(String, String)>) -> Self

Each tuple is (tag_name, metadata_key), e.g., ("h1", "Header 1").

pub fn default_headers() -> Self

Default configuration: split on h1, h2, h3.

pub fn split_html(&self, text: &str) -> Vec<Document>
