30-30: Approve the lint suppression, but consider a more specific approach.The addition of
#[allow(clippy::needless_return)]is acceptable as it likely addresses a false positive warning due to the#[rocketmq::main]attribute. However, consider the following suggestions:
Use a more specific attribute:
#[allow(clippy::needless_return)]applies to the entire function. If the warning is only for the finalOk(()), you could use#[allow(clippy::needless_return)]just for that line instead.Add a comment explaining why this lint is suppressed. This helps future maintainers understand the reasoning behind this decision.
Example:
#[rocketmq::main] // Suppress false positive from Clippy due to #[rocketmq::main] attribute #[allow(clippy::needless_return)] async fn main() -> anyhow::Result<()> { // ... function body ... Ok(()) // This return is necessary due to the function signature }
Line range hint
31-50: Consider improving error handling for theboot()method.The
mainfunction is well-structured and follows good practices. However, there's an opportunity to improve error handling for theboot()method. Currently, ifboot()fails, the error is silently ignored. Consider propagating any errors fromboot()to ensure robust error handling.Here's a suggested improvement:
#[rocketmq::main] #[allow(clippy::needless_return)] async fn main() -> anyhow::Result<()> { // ... existing code ... Builder::new() .set_name_server_config(namesrv_config) .set_server_config(ServerConfig { listen_port: args.port, bind_address: args.ip, }) .build() .boot() .await?; // Add ? to propagate any errors Ok(()) }This change ensures that any errors occurring during the boot process are properly handled and reported.

31-31: 🛠️ Refactor suggestionConsider the implications of suppressing the
needless_returnlint.The added attribute
#[allow(clippy::needless_return)]suppresses warnings about unnecessaryreturnstatements in themainfunction. While this reduces compiler noise, it's worth considering the following points:
- This attribute hides a style recommendation that could potentially improve code conciseness.
- The explicit
return Ok(())at the end ofmainis a common Rust idiom and can be considered more readable, justifying the use of this attribute.To ensure code quality and consistency:
- Verify if this approach aligns with the project's coding standards.
- Check if similar functions in the project use this attribute or follow a different style.
Alternatively, consider modifying the code to remove the explicit return:
#[rocketmq::main] async fn main() -> anyhow::Result<()> { // ... (existing code) ... Builder::new() .set_broker_config(broker_config) .set_message_store_config(message_store_config) .build() .boot() .await; Ok(()) }This change would eliminate the need for the attribute while maintaining the function's behavior. However, the current approach with the attribute is also valid if it aligns with the project's preferences for explicit returns.
