+/// Type of compilation used for benchmarking/profiling.
+// Note: This type is very similar to the definition of a profile in the database crate.
+// However, these types should not be unified, as they serve slightly different purposes.
+// This type is used for specifying profiles to be benchmarked using the CLI, which is not relevant
+// to the database crate.
+// In general, the database versions of types used in the collector should be considered a DB
+// implementation detail, as they may change when we alter database layout.
