ConnectionManager

Struct ConnectionManager 

Source
pub struct ConnectionManager { /* private fields */ }
Expand description

Central orchestrator for connection lifecycle management.

Wraps ClientConfig, EndpointList, ReconnectConfig, AtomicConnectionState and ConnectionHealth.

Implementations§

Source§

impl ConnectionManager

Source

pub fn new( config: ClientConfig, endpoints: EndpointList, reconnect_config: ReconnectConfig, ) -> Self

Create a new manager from config and endpoints.

Source

pub fn with_primary(config: ClientConfig) -> Self

Convenience: create with a single primary endpoint.

Source

pub fn with_health_check_interval(self, interval: Duration) -> Self

Set the health-check interval.

Source

pub fn on_state_change<F>(&self, f: F)
where F: Fn(ConnectionState, ConnectionState) + Send + Sync + 'static,

Set a state-change callback.

Source

pub fn state(&self) -> ConnectionState

Current connection state (lock-free).

Source

pub fn health(&self) -> ConnectionHealth

Snapshot of connection health.

Source

pub fn active_endpoint(&self) -> Option<String>

URL of the currently active endpoint, if any.

Source

pub fn endpoints(&self) -> EndpointList

Reference to endpoint list (read-locked).

Source

pub fn config(&self) -> &ClientConfig

Client config reference.

Source

pub async fn connect(&self) -> Result<()>

Initiate a connection attempt.

Walks the endpoint list in priority order. On the first success the state transitions to Connected. If all endpoints fail, the state moves to Failed.

Source

pub fn disconnect(&self)

Cleanly disconnect and reset state.

Source

pub async fn failover(&self) -> Result<String>

Manually trigger a failover to the next endpoint.

Source

pub fn enable_auto_reconnect(&self)

Enable automatic reconnection.

Source

pub fn disable_auto_reconnect(&self)

Disable automatic reconnection.

Source

pub fn is_auto_reconnect_enabled(&self) -> bool

Whether auto-reconnect is currently enabled.

Source

pub async fn reconnect_loop(&self) -> Result<()>

Run the reconnection loop (usually spawned as a background task). Tries endpoints with exponential backoff until success or max_attempts is exhausted.

Source

pub async fn check_health(&self) -> Result<()>

Run a single health check against the active endpoint.
