+# The Stylus team sets new crates with the following types:
+# `lib` - The default, which gets turned to `rlib` by cargo and is needed to
+# link the crate as a dependency of binaries.
+# `cdylib` - A dynamic system library to be loaded from `wasm`.
+#
+# See <https://doc.rust-lang.org/reference/linkage.html>
+#
+# This means our crate would be built twice: once as a rust library and once as
+# a dynamic library. When running `cargo test`, cargo invokes rustc twice, but
+# when it build the rust library, it doesn't set the `test` feature flag, so we
+# can't use it.
+#
+# The reason to add `lib` is to be able to use the `export-abi` feature of the
+# SDK. We don't set `lib` here because our contracts are meant to be used as an
+# addition to other contracts. For this use case, the abi of those contracts
+# will contain ours.
+# 
+# The trade-off is being able to run `cargo test` with conditional compilation
+# vs being able to run `cargo stylus export-abi`.
+# 
+# This may change in the future, so this behavior should not be relied upon.
