+This directory is the code generation target for the Positional model when targetting Rust.
+
+Like the other targets, the crate is a combination of the output of three different components:
+
+1. The output of Dafny code generation for Rust (`src/implementation_from_dafny.rs`)
+2. The output of `smithy-dafny` shim/conversion generation for Rust (the `conversions` module)
+3. The output of `smithy-rs` (all other files)
+
+Most of the `smithy-rs` output is not modified,
+only trimmed down to cut out components that aren't relevant for Polymorph libraries.
+The main exception is `client.rs` and the operation builders such as `operation/get_positional.rs`,
+which instantiate the underlying Dafny client implementation and invoke operations on it, respectively,
+instead of sending the operation value through an orchestrated plugin stack
+that eventually serializes it and sends it to a remote service endpoint.
+
+This crate also includes manually-written Rust tests demonstrating what it's like
+to work with the Rust API we're exposing.
+Although we need to also get the Dafny-generated tests working,
+the manually-written ones are also valuable.
+
+It looks likely that `smithy-rs` is pluggable enough that we can plug our conversion code generation
+into it without having to fork its implementation.
+This means we should be able to get 2. and 3. above out of a single call to `smithy-rs`.
+Hence I've optimistically left the "// Code generated by software.amazon.smithy.rust.codegen.smithy-rs. DO NOT EDIT."
+header on both kinds of files.
+
+Note that even 1. is hand-modified, as the Dafny Rust code generator is not yet complete,
+and rejects some features such as the type paramter variance specifier on `Option<+T>`.
+We are trusting that Dafny will soon generate exactly the content of `implementation_from_dafny.rs`
+and it is a priority to set up CI to assert that ASAP.
