Struct PubsubSourceConfig 

pub struct PubsubSourceConfig {
    pub subscription: String,
    pub connection: PubsubConnection,
    pub value_format: ValueFormat,
    pub attributes_key: String,
    pub max_messages_per_pull: usize,
    pub idle_termination_secs: Option<u64>,
    pub max_messages: Option<usize>,
    pub batch_size: usize,
}

Configuration for PubsubSource.

Fields

subscription: String

Subscription id (short name, not the fully-qualified path). The client forms projects/<project>/subscriptions/<id> from the connection’s project.

connection: PubsubConnection

Project / endpoint / emulator / credentials (flattened).

value_format: ValueFormat

Payload decoding for the message data field.

attributes_key: String

JSON key the message attribute map is surfaced under. Default __attributes.

max_messages_per_pull: usize

Messages requested per pull RPC (1–1000). Default 100.

idle_termination_secs: Option<u64>

Stop after this many seconds without a new message. At least one of idle_termination_secs and max_messages must be set (mirrors the Kafka / Kinesis sources) — a batch run must terminate.

max_messages: Option<usize>

Stop after this many messages in total.

batch_size: usize

Records per emitted StreamPage. 0 is the “no batching” sentinel: one page per drain. Default 1000. A page’s messages are acked once the pipeline has durably written the page.

Implementations

impl PubsubSourceConfig

pub fn new(subscription: impl Into<String>) -> Self

Minimal config with defaults for everything but the subscription id.

pub fn validate(&self) -> Result<(), FaucetError>

Fail-fast validation, called from PubsubSource::new.

Trait Implementations

impl Clone for PubsubSourceConfig

fn clone(&self) -> PubsubSourceConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PubsubSourceConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PubsubSourceConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for PubsubSourceConfig

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for PubsubSourceConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
