cbindgen not exporting rodbus public constants about rodbus HOT 5 CLOSED

I have raised an issue here to see how to proceed

from rodbus.

I defined the required constants directly in the FFI module. Not ideal in terms of duplication, but I will now remove the milestone tag so it doesn't block the release.

from rodbus.

The trick is the following:

[parse]
parse_deps = true
include = ["rodbus", "tokio"]
extra_bindings = ["rodbus"]

The parse_deps says to also read from dependent crates for stuff to export. It only exports what we use in rodbus-ffi, so you get the Channel (from rodbus) and the Runtime (from tokio). The include whitelists what we want to look at.

The extra_bindings exports all the public constants and public functions from the dependent crates listed. If we want to export the constants, we need this. However, it's all or nothing AFAIK.

from rodbus.

Nice find. It'd be nice if cbindgen could not only whitelist crates, but modules within crates... I guess I'm happy enough with duplicating the few constants in the FFI crate. I'll go update the ticket on the cbindgen project.

We don't use cbindgen anymore.
