Detailed Description

Configuration for header writing.

Mirrors HeaderWriterOptions (writer/header_writer.rs). write_index == false forces index_node_size to 0 at the point the header is actually built (M7), which is how the header says "no R-tree" – this struct itself does not enforce that, matching Rust's HeaderWriterOptions::new_with_options.

attribute_indices

std::vector<std::pair<std::string, std::optional<std::uint16_t> > > fcb::HeaderWriterOptions::attribute_indices

(attribute name, branching factor); std::nullopt branching factor means the default.

Empty means Rust's attribute_indices: None.
