wormhole-rs completion not working ?

[Matthias Geiger <werdahias@xxxxxxxxxx>]

Hi all,
I have an issue with a completion file not working correctly.
I'm the maintainer of wormhole-rs 
[0] in Debian, which 
is written in Rust and uses clap-complete (a rust library) during the 
build to generate the completion files. They work for bash and fish OOTB 
as expected. However, in zsh they don't and I want to know why.
If I type "wormhole-rs" and then hit TAB only filenames get completed. 
However, if I manually source the completion file (located under 
/usr/share/zsh/vendor-completions) and then type the same completion 
works as expected.
My .zshrc: [1]

Attached the generated completion file.
Is there something wrong with the generated file ? I suspect so, but 
would like to get some expertise.

best,

werdahias
