Updates the requirements on [aws-config](https://github.com/awslabs/smithy-rs) to permit the latest version. <details> <summary>Changelog</summary> <p><em>Sourced from <a href="https://github.com/awslabs/smithy-rs/blob/main/CHANGELOG.md";>aws-config's changelog</a>.</em></p> <blockquote> <!-- raw HTML omitted --> <h1>December 12th, 2022</h1> <p><strong>Breaking Changes:</strong></p> <ul> <li> <p>β π (all, <a href="https://github-redirect.dependabot.com/awslabs/smithy-rs/issues/1938";>smithy-rs#1938</a>, <a href="https://github.com/jjantdev";><code>@βjjantdev</code></a>) Upgrade Rust MSRV to 1.62.1</p> </li> <li> <p>β π (server, <a href="https://github-redirect.dependabot.com/awslabs/smithy-rs/issues/1199";>smithy-rs#1199</a>, <a href="https://github-redirect.dependabot.com/awslabs/smithy-rs/issues/1342";>smithy-rs#1342</a>, <a href="https://github-redirect.dependabot.com/awslabs/smithy-rs/issues/1401";>smithy-rs#1401</a>, <a href="https://github-redirect.dependabot.com/awslabs/smithy-rs/issues/1998";>smithy-rs#1998</a>, <a href="https://github-redirect.dependabot.com/awslabs/smithy-rs/issues/2005";>smithy-rs#2005</a>, <a href="https://github-redirect.dependabot.com/awslabs/smithy-rs/issues/2028";>smithy-rs#2028</a>, <a href="https://github-redirect.dependabot.com/awslabs/smithy-rs/issues/2034";>smithy-rs#2034</a>, <a href="https://github-redirect.dependabot.com/awslabs/smithy-rs/issues/2036";>smithy-rs#2036</a>) <a href="https://awslabs.github.io/smithy/2.0/spec/constraint-traits.html";>Constraint traits</a> in server SDKs are beginning to be supported. The following are now supported:</p> <ul> <li>The <code>length</code> trait on <code>string</code> shapes.</li> <li>The <code>length</code> trait on <code>map</code> shapes.</li> <li>The <code>length</code> trait on <code>list</code> shapes.</li> <li>The <code>range</code> trait on <code>byte</code> shapes.</li> <li>The <code>range</code> trait on <code>short</code> shapes.</li> <li>The <code>range</code> trait on <code>integer</code> shapes.</li> <li>The <code>range</code> trait on <code>long</code> shapes.</li> <li>The <code>pattern</code> trait on <code>string</code> shapes.</li> </ul> <p>Upon receiving a request that violates the modeled constraints, the server SDK will reject it with a message indicating why.</p> <p>Unsupported (constraint trait, target shape) combinations will now fail at code generation time, whereas previously they were just ignored. This is a breaking change to raise awareness in service owners of their server SDKs behaving differently than what was modeled. To continue generating a server SDK with unsupported constraint traits, set <code>codegenConfig.ignoreUnsupportedConstraints</code> to <code>true</code> in your <code>smithy-build.json</code>.</p> </li> <li> <p>β π (server, <a href="https://github-redirect.dependabot.com/awslabs/smithy-rs/issues/1342";>smithy-rs#1342</a>, <a href="https://github-redirect.dependabot.com/awslabs/smithy-rs/issues/1119";>smithy-rs#1119</a>) Server SDKs now generate "constrained types" for constrained shapes. Constrained types are <a href="https://rust-unofficial.github.io/patterns/patterns/behavioural/newtype.html";>newtypes</a> that encapsulate the modeled constraints. They constitute a <a href="https://www.lpalmieri.com/posts/2020-12-11-zero-to-production-6-domain-modelling/";>widespread pattern to guarantee domain invariants</a> and promote correctness in your business logic. So, for example, the model:</p> <pre lang="smithy"><code>@length(min: 1, max: 69) string NiceString </code></pre> <p>will now render a <code>struct NiceString(String)</code>. Instantiating a <code>NiceString</code> is a fallible operation:</p> <pre lang="rust"><code>let data: String = ... ; let nice_string = NiceString::try_from(data).expect("data is not nice"); </code></pre> <p>A failed attempt to instantiate a constrained type will yield a <code>ConstraintViolation</code> error type you may want to handle. This type's API is subject to change.</p> <p>Constrained types <em>guarantee</em>, by virtue of the type system, that your service's operation outputs adhere to the modeled constraints. To learn more about the motivation for constrained types and how they work, see <a href="https://github-redirect.dependabot.com/awslabs/smithy-rs/pull/1199";>the RFC</a>.</p> <p>If you'd like to opt-out of generating constrained types, you can set <code>codegenConfig.publicConstrainedTypes</code> to <code>false</code>. Note that if you do, the generated server SDK will still honor your operation input's modeled constraints upon receiving a request, but will not help you in writing business logic code that adheres to the constraints, and <em>will not prevent you from returning responses containing operation outputs that violate said constraints</em>.</p> </li> <li> <p>πβ π (server, <a href="https://github-redirect.dependabot.com/awslabs/smithy-rs/issues/1714";>smithy-rs#1714</a>, <a href="https://github-redirect.dependabot.com/awslabs/smithy-rs/issues/1342";>smithy-rs#1342</a>) Structure builders in server SDKs have undergone significant changes.</p> <p>The API surface has been reduced. It is now simpler and closely follows what you would get when using the <a href="https://docs.rs/derive_builder/latest/derive_builder/";><code>derive_builder</code></a> crate:</p> <ol> <li>Builders no longer have <code>set_*</code> methods taking in <code>Option<T></code>. You must use the unprefixed method, named exactly after the structure's field name, and taking in a value <em>whose type matches exactly that of the structure's field</em>.</li> <li>Builders no longer have convenience methods to pass in an element for a field whose type is a vector or a map. You must pass in the entire contents of the collection up front.</li> <li>Builders no longer implement <a href="https://doc.rust-lang.org/std/cmp/trait.PartialEq.html";><code>PartialEq</code></a>.</li> </ol> <p>Bug fixes:</p> <ol start="4"> <li>Builders now always fail to build if a value for a <code>required</code> member is not provided. Previously, builders were falling back to a default value (e.g. <code>""</code> for <code>String</code>s) for some shapes. This was a bug.</li> </ol> </li> </ul> <!-- raw HTML omitted --> </blockquote> <p>...
