26-27: Clarify the usage of the#[trait_variant::make]macroThe macro
#[trait_variant::make(PopCallback: Send)]generates a variant of the traitPopCallbackInnernamedPopCallbackwith theSendmarker trait. This may not be immediately clear to other developers unfamiliar with thetrait_variantcrate or the macro's functionality.Consider adding documentation or comments explaining the purpose and effect of this macro to improve code readability and maintainability.

47-67:
Ensure consistency between trait names in implementation
In the implementation block, you are implementing PopCallback for any function F, but the methods refer to PopCallbackInner. This could lead to confusion about which trait is being implemented.
Apply this diff to correct the trait name in the implementation:
-impl<F, Fut> PopCallback for F
+impl<F, Fut> PopCallbackInner for F
where
F: Fn(PopResult) -> Fut + Send + Sync,
Fut: Future<Output = ()> + Send,
{
/// Calls the function with the pop result when the pop operation is successful.
async fn on_success(&self, pop_result: PopResult) {
(*self)(pop_result).await;
}
/// Does nothing when the pop operation encounters an error.
fn on_error(&self, e: Box<dyn std::error::Error>) {}
}Alternatively, if PopCallback is the intended trait name, ensure that it is consistently used throughout the codebase and that PopCallbackInner is correctly aliased or removed if unnecessary.
Likely invalid or redundant comment.
118-137:
Use the correct method to invoke the callback function
In the test pop_callback_fn_on_success_called, the callback function is being called directly but may not handle errors properly or conform to the intended usage.
Apply this diff to ensure the callback is used correctly:
- callback_fn(pop_result).await;
+ callback_fn.on_success(pop_result).await;Ensure that callback_fn implements the PopCallbackInner trait so that you can call on_success and on_error methods appropriately.
Likely invalid or redundant comment.

🛠️ Refactor suggestion
Handle errors appropriately in on_error implementation
Currently, the on_error method does nothing when an error occurs. Silently ignoring errors can make debugging difficult and might hide issues during runtime.
Consider adding error handling or logging within the on_error method to capture and manage errors effectively. For example:
fn on_error(&self, e: Box<dyn std::error::Error>) {
- // Do nothing
+ eprintln!("Pop operation encountered an error: {}", e);
}📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
| fn on_error(&self, e: Box<dyn std::error::Error>) {} | |
| fn on_error(&self, e: Box<dyn std::error::Error>) { | |
| eprintln!("Pop operation encountered an error: {}", e); | |
| } |
| async fn on_success(&self, _pop_result: PopResult) { | ||
| // Mock implementation | ||
| } | ||

| fn on_error(&self, _e: Box<dyn Error>) { | ||

🛠️ Refactor suggestion
Implement assertions in test methods to verify behavior
The test methods pop_callback_on_success_called and pop_callback_on_error_called currently lack assertions to verify the expected behavior of the callbacks. Without assertions, the tests may not effectively validate the code.
Add assertions or mock behaviors to confirm that the callbacks are functioning as intended. For example:
async fn on_success(&self, _pop_result: PopResult) {
// Mock implementation
+ println!("on_success called");
}
fn on_error(&self, _e: Box<dyn Error>) {
// Mock implementation
+ println!("on_error called");
}And then in your tests, you can capture the output or use a shared state to assert that the methods were called.
Alternatively, use a testing framework or mocking library to verify that the methods are invoked correctly.
