Walkthrough

Introduces a new AuthenticationMetadataProvider trait for user management operations with async lifecycle and CRUD methods. The trait is declared in a new module and re-exported across multiple levels of the crate's module hierarchy to expose it through the public API.

Changes

Cohort / File(s)	Change Summary
New Trait Definition rocketmq-auth/src/authentication/provider/authentication_metadata_provider.rs	Introduces new public async trait AuthenticationMetadataProvider (Send + Sync) with seven methods: initialize(), shutdown(), create_user(), delete_user(), update_user(), get_user(), list_user(). All methods use RocketMQResult for error handling and include documentation comments.
Module Declarations & Re-exports rocketmq-auth/src/authentication/provider.rs, rocketmq-auth/src/authentication.rs, rocketmq-auth/src/lib.rs	Declares new module authentication_metadata_provider, adds public re-export from provider module, re-exports from authentication module, and exposes trait at crate root via lib.rs. All are simple, non-behavioral additions to the public API surface.

rocketmq-auth/src/authentication/provider.rs (1)

20-23: Stale comment: no #[path] attributes are used.

The comment on line 20 mentions #[path] attribute, but the code uses standard module declarations without path attributes. Consider updating or removing this comment to avoid confusion.

🔎 Suggested fix

-// Declare submodules using #[path] attribute
-
+// Declare submodules
 pub mod authentication_metadata_provider;
 pub mod authentication_provider;

rocketmq-auth/src/authentication/provider/authentication_metadata_provider.rs (1)

58-59: Consider renaming list_user to list_users for consistency.

The method returns Vec<User> (plural), so the method name should reflect that it returns multiple users.

🔎 Suggested fix

-    /// List users with optional filter.
-    async fn list_user(&self, filter: Option<&str>) -> RocketMQResult<Vec<User>>;
+    /// List users with optional filter.
+    async fn list_users(&self, filter: Option<&str>) -> RocketMQResult<Vec<User>>;

🔇 Additional comments (5)

rocketmq-auth/src/authentication.rs (1)

28-28: LGTM!

The re-export follows the existing pattern for AuthenticationProvider and AuthenticationStrategy, maintaining consistency in the public API exposure.

rocketmq-auth/src/lib.rs (1)

27-27: LGTM!

The crate-level re-export correctly exposes the new trait alongside the existing AuthenticationProvider, maintaining a consistent public API.

rocketmq-auth/src/authentication/provider.rs (1)

26-27: LGTM!

The re-exports correctly expose both provider traits, following the established module structure.

rocketmq-auth/src/authentication/provider/authentication_metadata_provider.rs (2)

34-44: Consider object safety implications with async trait methods.

Using #[allow(async_fn_in_trait)] is acceptable for Rust 1.75+, but note that this trait will not be object-safe (cannot use dyn AuthenticationMetadataProvider) due to the async methods. If dynamic dispatch is needed in the future, consider using the async-trait crate instead.

The &mut self receiver for initialize and shutdown is appropriate for lifecycle operations that may modify internal state.

---

46-56: LGTM on CRUD method signatures.

The CRUD operations correctly use &self since they don't require mutable access to the provider itself (mutations happen in the underlying storage). The API is clean and follows standard patterns.
