+
+A rule for transforming the outputs of `ProstGenProto` actions.
+
+This rule is used by adding it to the `data` attribute of `proto_library` targets. E.g.
+```python
+load("@rules_proto//proto:defs.bzl", "proto_library")
+load("@rules_rust_prost//:defs.bzl", "rust_prost_library", "rust_prost_transform")
+
+rust_prost_transform(
+    name = "a_transform",
+    srcs = [
+        "a_src.rs",
+    ],
+)
+
+proto_library(
+    name = "a_proto",
+    srcs = [
+        "a.proto",
+    ],
+    data = [
+        ":transform",
+    ],
+)
+
+rust_prost_library(
+    name = "a_rs_proto",
+    proto = ":a_proto",
+)
+```
+
+The `rust_prost_library` will spawn an action on the `a_proto` target which consumes the
+`a_transform` rule to provide a means of granularly modifying a proto library for `ProstGenProto`
+actions with minimal impact to other consumers.
