… HA implementation✨
WalkthroughThis change introduces new general and AutoSwitch High Availability (HA) components, including unified client and connection managers, and expands module declarations for better organization. It adds struct definitions and trait stubs for AutoSwitch HA, updates initialization logic for DefaultHAService, and ensures proper service integration and modular separation for HA strategies.

23-24: LGTM! Clean module organization.The new module declarations follow the existing pattern and use appropriate visibility for internal crate access.
rocketmq-store/src/ha/auto_switch.rs (1)
17-18: Good architectural organization.The new module declarations complete the auto-switch HA component trio (service, client, connection) and follow consistent naming conventions.
rocketmq-store/src/ha/general_ha_service.rs (1)
52-54: Excellent initialization pattern.The updated initialization logic properly creates a mutable instance, initializes it with error handling, and only assigns after successful initialization. This follows good initialization practices.

GeneralHAConnection struct has private fields without any constructor or

with given DefaultHAConnection and AutoSwitchHAConnection options, and implement

Fix naming inconsistency between field names and types.
The field names use "service" suffix but the types are "Client" types. This creates confusion and should be corrected for consistency.

Replace todo!() stubs with basic implementations to prevent runtime panics.
All methods currently use todo!() which will panic if called. Consider implementing basic functionality or at least safe defaults to make the code usable during development.

impl HAClient for AutoSwitchHAClient {

+ println!("AutoSwitchHAClient: start() called");
}
async fn shutdown(&self) {

In rocketmq-store/src/ha/auto_switch/auto_switch_ha_client.rs between lines 24
and 75, all methods currently use todo!() which causes runtime panics if called.
Replace these todo!() stubs with basic implementations or safe default returns
to prevent panics during development. For async methods, provide minimal async
blocks that do nothing or log a placeholder; for getters, return default values
like empty strings or zero; for state-related methods, return a default
HAConnectionState or update an internal state variable accordingly. This will
make the code safe to call and easier to extend later.
