pub fn codegen(path: &str) -> Result<Codegen, String>Expand description
Runs yog ui gen <path> in the file’s folder, so a saved screen’s
generated foo.g.rs is current without a full build (yog finds the
project from the yog.toml above the file). The result carries what
yog printed either way — its errors and warnings go to the Error List;
Err only when yog couldn’t run at all.
