Add rust-toolchain.toml (#1861) 2022-10-19 21:51:00 +08:00			`[toolchain]`
Upgrade MSRV to 1.78.0 (#3800) ## Motivation and Context Upgrades MSRV to 1.78.0 since the [latest Rust](https://www.rust-lang.org/) at the time of writing is 1.80.1 (we try keeping [two releases behind](https://github.com/awslabs/aws-sdk-rust?tab=readme-ov-file#supported-rust-versions-msrv)). ## Description In Rust 1.78.0, `clippy` enforces stricter checks in two areas: - `dead_code` It seems to be able to uncover more unused code patterns, especially when different combinations of cargo features are enabled - `empty_docs` Prior to 1.78.0, the codegen used to render the following empty docs `///`, regardless whether the codegen is for the server or for the client. This is now flagged as `empty_docs` by `clippy`: ``` /// pub(crate) mod XXX { ... } ``` Other than bumping MSRV to 1.78.0, the remaining code changes address issues related to the fixes mentioned above. EDIT: `cargo-semver-checks` required an upgrade due to incompatibility issues following the MSRV upgrade ([example error](https://github.com/smithy-lang/smithy-rs/actions/runs/10534205294/job/29261105195#step:4:2068)). Specifically, after updating the MSRV to 1.78.0, the rustdoc version was upgraded to v28. However, the version of `cargo-semver-checks` we were using (0.24.1) only supported rustdoc [up to v27](https://github.com/obi1kenobi/cargo-semver-checks/blob/4bce03d4a6a32cf651b9eccddb40e3418dc2c154/Cargo.toml#L18). To resolve this, we have updated `cargo-semver-checks` to the first version that supports rustdoc [v28](https://github.com/obi1kenobi/cargo-semver-checks/blob/94a491f0854f0bdbccbb301099db119201bff181/Cargo.toml#L18). ## Testing Existing tests in CI ## Checklist <!--- If a checkbox below is not applicable, then please DELETE it rather than leaving it unchecked --> - [x] For changes to the smithy-rs codegen or runtime crates, I have created a changelog entry Markdown file in the `.changelog` directory, specifying "client," "server," or both in the `applies_to` key. - [x] For changes to the AWS SDK, generated SDK code, or SDK runtime crates, I have created a changelog entry Markdown file in the `.changelog` directory, specifying "aws-sdk-rust" in the `applies_to` key. ---- _By submitting this pull request, I confirm that you can use, modify, copy, and redistribute this contribution, under the terms of your choice._ 2024-08-27 23:30:40 +08:00			`channel = "1.78.0"`
