@l3r8yJ what do you mean by structs and types here? We have github-mirror workspace member that generates all GitHub-compatible structs we operate with in server. In server we have mostly objects that deal with logic/generated structs

@h1alexbel I'll send a POC pr a bit later

@l3r8yJ If you refer to rather a config state inside FakeHub, we need to name it properly. I suggest fss - Fakehub State Structs. This crate will be a dependency for fsl crate. WDYT?
