• external-harfbuzz: activates the same-named feature in the tectonic_bridge_harfbuzz dependency.

Updating the generated headers

This crate exposes Rust functions to C/C++ code using a header file created by cbindgen. To update the header, run:

cbindgen --output xetex/xetex_bindings.h

It also uses definitions generated by the tectonic_xetex_format introspection crate. To update that header, run:

cargo run -p tectonic_xetex_format --example emit >xetex/xetex_format.h

Note that this crate defines the format serial number that it implements (in tectonic_engine_xetex::FORMAT_SERIAL) separately from the maximum serial number supported by the introspection crate (in tectonic_xetex_format::LATEST_VERSION).
