Struct ClusterConfig 

pub struct ClusterConfig {
    pub node_id: u32,
    pub listen_address: SocketAddr,
    pub initial_cluster: Vec<NodeMeta>,
    pub db_root_dir: PathBuf,
    pub log_dir: PathBuf,
}

Cluster node configuration parameters

Encapsulates all essential settings for cluster node initialization and operation, including network settings, storage paths, and cluster topology.

Defaults

Configuration can be loaded from file with default values generated via serde’s default implementations. Field-level defaults use helper functions prefixed with default_.

Fields

node_id: u32

Unique node identifier in cluster

Default: default_node_id() (typically 0 for single-node setup)

listen_address: SocketAddr

Network listening address (IP:PORT)

Default: default_listen_addr() (127.0.0.1:8000)

initial_cluster: Vec<NodeMeta>

Seed nodes for cluster initialization

Default: default_initial_cluster() (empty vector)

Note

Should contain at least 3 nodes for production deployment

db_root_dir: PathBuf

Database storage root directory

Default: default_db_dir() (/tmp/db)

log_dir: PathBuf

Log files output directory

Default: default_log_dir() (./logs)
