[StackOverflow/rust] How to configure a connection to GridDB using the Rust client (notification_member vs notification_provider)?

### ROOT CAUSE The user is confused about the difference between `notification_member` and `notification_provider` when configuring a GridDB connection in Rust. GridDB's Rust client requires specifying the correct role (member or provider) for notifications, but the documentation may not clearly distinguish their usage in the Rust context. The issue arises from unclear client configuration options, not necessarily a bug. --- ### CODE FIX Configure the GridDB connection based on the required role (member or provider) using the Rust client's `connect` method with the `NotificationConfig` struct. Here's how: 1. **As a Notification Member** (subscribes to notifications): ```rust use griddb::prelude::*; let config = NotificationConfig::new() .with_member_name("my_member") .with_container_name("my_container"); let client = Client::connect("localhost", 62626, &config).await?; ``` 2. **As a Notification Provider** (publishes notifications): ```rust let config = NotificationConfig::new() .with_provider_name("my_provider") .with_container_name("my_container"); let client = Client::connect("localhost", 62626, &config).await?; ``` **Explanation**: - `NotificationConfig::new()` initializes the configuration. - Use `.with_member_name()` for subscribers and `.with_provider_name()` for publishers. - Ensure the GridDB cluster is running and the container exists. **Note**: Check the GridDB Rust client documentation for exact method signatures. If the client library doesn’t support these config options, consult GridDB’s Rust integration guide or file an issue with the maintainers.
