### How do I store additional information about nodes in Openraft?
By default, Openraft provide a [`BasicNode`] as the node type in a cluster.
To store more information about each node in Openraft, define a custom struct
with the desired fields and use it in place of `BasicNode`. Here's a brief
guide:
1. Define your custom node struct:
```rust,ignore
#[derive(...)]
struct MyNode {
ipv4: String,
ipv6: String,
port: u16,
// Add additional fields as needed
}
```
2. Register the custom node type with `declare_raft_types!` macro:
```rust,ignore
openraft::declare_raft_types!(
pub MyRaftConfig:
// ...
NodeId = u64, // Use the appropriate type for NodeId
Node = MyNode, // Replace BasicNode with your custom node type
// ... other associated types
);
```
Use `MyRaftConfig` in your Raft setup to utilize the custom node structure.
