Any recommended pointers to examples of how to use rustc without cargo
I dislike the tone of the evangelism and the anti-C attitude but I'm not anti-rust. I purchased a computer with an oversized amount or RAM in part so I could experiment with rust. But determining how to write, edit and compile small programs, from the ground up, without cargo appears exceedingly difficult, and feels like going against the tide
It stands to reason that the embedded programmer commenting was unable to determine how to avoid using cargo and pulling in unnecessary dependencies. Otherwise he would not have encountered this problem
Definitely going against the tide; but possible
e.g. Chrome & Fuchsia both build included Rust bits using their existing build system.
Bazel and Buck2 both work well with it, relatively.
One can also just be really disciplined with Cargo and not add superfluous deps and be careful about the ones you do include to monitor their transitive dependencies.
IMHO this is more about crates.io than Cargo, and is the biggest weakness of the language community. A bulk of developers unfortunately I think come from an NPM-using background and so aren't philosophically ... attuned... to see the problem here.
