There are a few mpegtsmux examples in C however nothing in rust.
You're looking for the usage of the API from libgstmpegts from Rust? There are only unsafe FFI bindings for that library currently, mostly because the API is very bindings unfriendly.
You can write your application as usual with Rust and the bindings, and for accessing the API of that library you'd need to use some unsafe code. That would then basically look like the C code you linked, plus the relevant translations between Rust and C types.
Does this help answering your question?
Furthermore, has anyone muxed in a teletext stream using appsrc with Pad template application/x-teletext: ?
What problems are you running into?
I'm putting together a tsmuxer for a DATV project. (Digital Amateur TV) similar to IPTV.
I was hoping there was a rust example with using the gstreamer mpegtsmux element to show its full glory.
The later releases 1.18.4 indicates a lot of work done yo get mpegtsmux DVB compliant supporting most of the SI tables, PMT, NIT, PAT and CBR!! Only FFMPEG or opencaster was the only ones available in freeware.

Here's an example using gst-launch-1.0 however limited to the fact you can't set pat-interval, pmt-interval etc.. I maybe wrong?
gst-launch-1.0 -v filesrc location=/media/myfile.ts ! tsdemux name=demux program-number=10 demux.video_012c ! queue ! mux.sink_300 mpegtsmux name=mux prog-map=program_map,sink_300=10,sink_302=10,sink_303=10,sink_301=10 ! rtpmp2tpay ! udpsink host=127.0.0.1 port=8000 demux.metadata_012f ! queue ! mux.sink_303
And
gst-launch-1.0 -vm --gst-plugin-path=./gstreamer-media-SDK/build/gst/mfx videotestsrc is-live=true pattern=zone-plate kx2=20 ky2=20 kxy=4 kt2=10 ! queue ! video/x-raw, format=I420,width=1280,height=720 ! queue ! videoconvert ! queue ! mfxhevcenc rate-control=cbr bitrate=10000 gop-size=32 idr-interval=1 async-depth=1 gop-distance=4 ! queue ! mux.sink_100 mpegtsmux name=mux prog-map=program_map,sink_100=1 ! queue ! tsparse ! queue ! udpsink name=udpsink port=1234 host=239.141.50.1 max-bitrate=120000000

Love to know how you got it to work. I tried however just couldn't get it to work maybe need constant time stamping to Video PCR.
A rust example for both would be appreciated. 😁
