Struct WebSocketSourceConfig 

Source 
pub struct WebSocketSourceConfig {
    pub mode: SourceMode,
    pub format: MessageFormat,
    pub on_backpressure: BackpressureStrategy,
    pub event_time_field: Option<String>,
    pub event_time_format: Option<EventTimeFormat>,
    pub max_message_size: usize,
    pub auth: Option<WsAuthConfig>,
}
Expand description

WebSocket source connector configuration.

Supports two operating modes:

  • Client: connects to one or more upstream WebSocket servers and optionally sends a subscribe message after the handshake.
  • Server: binds a local address and accepts incoming WebSocket connections (e.g., from IoT devices or browser clients).

Fields§

§mode: SourceMode

Operating mode (client or server).

§format: MessageFormat

Message format used for deserialization.

§on_backpressure: BackpressureStrategy

Backpressure strategy when the Ring 0 channel is full.

§event_time_field: Option<String>

JSON field path used to extract event time from each message.

When None, processing time is used as the event timestamp.

§event_time_format: Option<EventTimeFormat>

Format of the event time value extracted from event_time_field.

§max_message_size: usize

Maximum accepted WebSocket message size in bytes.

Messages exceeding this limit are rejected. Defaults to 64 MiB.

§auth: Option<WsAuthConfig>

Optional authentication configuration for the WebSocket connection.

Implementations§

Source§

impl WebSocketSourceConfig

Source

pub fn from_config(config: &ConnectorConfig) -> Result<Self, ConnectorError>

Builds a WebSocketSourceConfig from a flat ConnectorConfig property map.

Maps well-known keys from WITH (...) clauses to the structured config. Unknown keys are silently ignored (forward compatibility).

§Errors

Returns ConnectorError::ConfigurationError if a required key is missing or a value cannot be parsed.
