It's needed to get the C symbols that we translate to rust, similar to brotli: https://github.com/Cpp2Rust/cpp2rust/tree/master/rules/brotli/brotli
This is the origin: https://github.com/rustls/rustls-ffi/blob/main/librustls/src/rustls.h
I installed the deb package (https://github.com/rustls/rustls-ffi/releases/tag/v0.15.3) for rustls-ffi on my system and copied /usr/include/rustls.h into rules/rustls/rustls.h

I also had to add support in Mapper for rules of typedef'ed scalars.
For exmaple:
Would clash with the already-existing rule of int because ToString strips the typedef and returns int instead of rustls_io_result. GetNameOfScalarTypedef returns
rustls_io_resultand the mapping becomes:Initially I wanted to modify ToString to not strip the typedef, but that's a bigger change than I expected because it affects typedefs as
size_t,uint32_t, etc.
