Struct PubsubConnection 

pub struct PubsubConnection {
    pub project_id: Option<String>,
    pub endpoint: Option<String>,
    pub emulator_host: Option<String>,
    pub credentials: PubsubCredentials,
}

Available on crate features source-pubsub and source-rest only.

Connection settings shared by the Pub/Sub source and sink. Flattened into each connector config via #[serde(flatten)], so project_id / endpoint / emulator_host / credentials appear at the config top level.

Fields

project_id: Option<String>

GCP project id that owns the topic / subscription. Required for real Pub/Sub; the emulator infers it from PUBSUB_PROJECT_ID when unset.

endpoint: Option<String>

Override the Pub/Sub API endpoint (host:port or URL). Rarely needed — prefer emulator_host for the emulator.

emulator_host: Option<String>

Point the client at a Pub/Sub emulator (host:port). When set, auth is skipped and the endpoint is taken from this value — mirrors the PUBSUB_EMULATOR_HOST environment variable the SDK honours.

credentials: PubsubCredentials

How to authenticate. Defaults to Application Default Credentials.

Implementations

impl PubsubConnection

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

Effective emulator host: the explicit config value, else the PUBSUB_EMULATOR_HOST environment variable. None = real Pub/Sub.

Trait Implementations

impl Clone for PubsubConnection

fn clone(&self) -> PubsubConnection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PubsubConnection

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

Formats the value using the given formatter.

impl Default for PubsubConnection

fn default() -> PubsubConnection

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PubsubConnection

fn deserialize<__D>( __deserializer: __D, ) -> Result<PubsubConnection, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for PubsubConnection

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 PartialEq for PubsubConnection

fn eq(&self, other: &PubsubConnection) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for PubsubConnection

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
