+Projects can declare multiple Rust artifacts in one hook. Artifact `name` is the
+Cargo output stem used for exact file discovery, and `crate-type` defaults to
+`cdylib`. A destination containing `{python_extension_name}` packages that
+`cdylib` as a Python extension module; other Rust artifact destinations package
+the platform shared library name for standalone C ABI consumers.

 ### Generated files and headers
 
-`command` artifacts run an argv-list command and then validate explicit outputs.
-Outputs can be packaged into the wheel, installed as wheel shared data, or used
-only as required validation checks. `header` artifacts are a typed shorthand for
-validated header outputs and can also use `generator = "cbindgen"` in CLI or
-build-script mode.

+for generated headers, either on a command artifact or on the Rust artifact whose
+build produced the file.

 ### ABI validation and artifact metadata
 
-Shared-library artifacts can validate the copied C ABI library before the wheel
-is finalized. The hook can check expected exported symbols, verify headers and
-ABI strings/macros, load the copied library with `ctypes.CDLL`, run project
-validation commands, include Windows import libraries, and emit a package-local
-artifact manifest.
+`cdylib` artifacts can validate the copied C ABI library before the wheel is
+finalized. The hook can check expected exported symbols, verify headers and ABI
+strings/macros, load the copied library with `ctypes.CDLL` when `validate = true`,
+run project validation commands, include Windows import libraries, and emit a
+package-local artifact manifest.
