If you compile a crate with rust-gpu but forget to add

[lib]
crate-type = ["lib", "dylib"]

in it's cargo.toml rust-gpu will error out with: Artifact created when compilation succeeded.
This Error is outright wrong: What actually happened is that compilation succeeded but NO *.spv artifact was found.

The error is thrown in crates/spirv-builder/src/lib.rs line 538, at the end of the invoke_rustc() method.
I'd like to suggest replacing this message with Compilation succeeded but no .spv Artifact was created! Make sure the crate-type includes \"dylib\".

Ouvrez crates/spirv-builder/src/lib.rs et examinez la ligne 538 à la fin de invoke_rustc(). Confirmez comment le cas sans artefact est atteint une fois la compilation réussie. C'est terminé lorsque le message d'erreur explique précisément qu'aucun artefact .spv n'a été créé et indique le paramètre crate-type requis.
