Replace #[allow] with parameter struct in bind_std_listener function

[coderabbitai]

Problem

The bind_std_listener function in src/server/config.rs currently uses #[allow(clippy::too_many_arguments)] to suppress the lint warning, which violates our coding guidelines that forbid #[allow] directives.

Solution

Replace the #[allow] directive by grouping related parameters into a struct:

• Create a BindConfig<F, T> struct containing: factory, workers, on_preamble_success, on_preamble_failure, and ready_tx
• Update the function signature to accept BindConfig<F, T> and std_listener as parameters
• Adjust the function body to use struct fields instead of individual parameters
• Update the bind_with_std_listener method to construct the config struct

Context

This issue was identified during code review of PR #262 in this comment.

Issue: #273

Files affected

• src/server/config.rs (lines 196-222)

@coderabbitai looking at the codebase, is this issue still relevant? If the issue has been fixed in the code, does the documentation reflect this?

If it is still relevant, please provide an assessment of the issue criticality (critical, high, medium or low), based on risk of the issue impacting the user and the anticipated blast radius.\n\nOnce a decision has been made, apply the appropriate label.

If the issue is documentation ONLY (i.e., no code changes needed), apply the documentation label in addition to the appropriate criticality label.

Please also provide an impact of the required changes.

Issue resolved by PR #325. The bind_std_listener function has been refactored and no longer uses #[allow(clippy::too_many_arguments)]. Documentation is current.

@leynos, issue #273 has already been resolved in the codebase.

Current Status

The issue was fixed by PR #325 ("Group listener binding parameters"), which was merged on 2025-08-21. The refactoring eliminated the #[allow(clippy::too_many_arguments)] directive by restructuring the binding logic.

What Changed

1. Original problem: The bind_std_listener function used #[allow(clippy::too_many_arguments)] to suppress lint warnings
2. Current implementation: The code now uses bind_to_listener in src/server/config/binding.rs with a clean signature that accepts only self and std_listener
3. No lint suppressions: No #[allow] directives exist in src/server/ directory

Documentation Status

The documentation is up-to-date. The file docs/server/configuration.md accurately reflects the current binding implementation with a sequence diagram showing the bind_to_listener flow.

Action

Closing this issue as the requested refactoring has been completed.
