The ideal form for introduction to anyone, would be to assume no acronyms or contractions… expand first instance of each. Even Client Libs could.should be noted is Client Libraries?.. if I knew nothing, would it all parse?.. so, first instance of Rust is Rust Programming Language, with a link out perhaps to what is Rust wiki somewhere nice and easy. If it’s all soft and squishy then it’ll be like quicksand and suck noobs in… exciting them that they understand it all! If you want to overdo it, there are tools to measure reading age, which for the current perhaps would tempt moderate techy awareness required… depends the audience how much you need to spell out. For me it’s fairly good as is.
