Poem

A whisker-twitched hop through the code so neat, 🐰
Removed a sleepy file, now tidy and fleet,
No traits in the wild, just comments that stayed,
The queue breathes a little, the clutter allayed.

Pull request overview

Removes the unused referred_iterator.rs module from rocketmq-store as part of issue #6334 cleanup.

Changes:

• Deleted rocketmq-store/src/queue/referred_iterator.rs (previously only contained commented-out code).

Comments suppressed due to low confidence (1)

rocketmq-store/src/queue/referred_iterator.rs:1

• This file is being removed, but rocketmq-store/src/queue.rs still declares pub mod referred_iterator; (line 33). As-is, the crate will fail to compile because the module file no longer exists. Remove the module declaration (and any re-exports) or keep an empty referred_iterator.rs stub if the module path must remain stable.
