Linter: Warn when number primitive is annotated with #[ink(topic)]
#1837
Conversation
The problem with suppressions is that `rustc` saves the state of the last visited node and checks its attributes to decide if the lint warning should be suppressed there (see: [LateContext::last_node_with_lint_attrs](https://github.com/rust-lang/rust/blob/c44324a4fe8e96f9d6473255df6c3a481caca76f/compiler/rustc_lint/src/context.rs#L1105)). This commit adds a call to the utility function from clippy that checks if the lint is suppressed for the field definition node, not for the last node (which is `Topics` impl).
Rework the lint after use-ink#1827

Overall, looks very good. We just need to decide whether to merge it as a minor patch of the ink! 4, or make it compatible with Events 2.0 and merge it in ink! 5.
I personally think we should make it work with Event 2.0 as ink! 5.0 might be released soon, and we will still have to add support for the new event definition.

Please update ref of clippy_utils to 1d334696587ac22b3a9e651e7ac684ac9e0697b2 and bump dylint_linting & dylint_testing to 2.1.12

You also need to set channel to nightly-2023-08-10 in rust-toolchain.toml

Done.
I updated clippy_utils version to 1d334696587ac22b3a9e651e7ac684ac9e0697b2 and set channel to nightly-2023-07-14 in rust-toolchain.toml. nightly-2023-07-14 is required, since this version is used in rust-clippy at commit 1d334696587ac22b3a9e651e7ac684ac9e0697b2.
How should we choose the clippy version for linting? Should we always take the latest version from the clippy master branch?

Not sure what you mean by clippy here. If you are referring to clippy_utils, I've been following a template in dylint repo

By clippy I mean the rust-clippy repository, which contains the clippy_utils crate. In this repo they set the toolchain version to nightly-2023-07-14 for all the crates. So we need to set the same version in our toolchain file to build clippy.

AFAIK we only have rust-toolchain.toml for the lining crate
