What's the motivation? Is it related to a problem? Please describe the background and rationale.
Given a C struct, it's tedious to manually write WASM C guest code to transform it into JSON format. We should be able to write a tool to accept a C struct name, or a header file, and generate the WASM C guest code, and compile it into .wasm binary code.
This .wasm binary code can then be directly executed on the Starship platform.
In other words, given a C struct outputted from eBPF, Starship can automatically output it into JSON format and write into database.
Describe the solution you'd like
We can use the existing C struct bindgen to produce the C code, and generate the WASM C code, to produce the c json output code. This is already part of C struct bind gen
Additional context, for example, Kubernetes versions, Kernel versions etc.
This is similar to a previous version of eunomia-bpf's automated JSON output feature.
