Struct GcsConfig 

pub struct GcsConfig {
    pub endpoint: Option<String>,
    pub bucket: String,
    pub tcp_user_timeout: Duration,
    pub cogs: Option<CostTrackerStreamConfig>,
}

Configuration for GcsBackend.

Stores objects in Google Cloud Storage. Authentication uses Application Default Credentials (ADC), which can be provided via the GOOGLE_APPLICATION_CREDENTIALS environment variable or the GCE/GKE metadata service.

Note: The bucket must be pre-created with the following lifecycle policy:

• daysSinceCustomTime: 1 day
• action: delete

Example

storage:
  type: gcs
  bucket: objectstore-bucket

Fields

endpoint: Option<String>

Optional custom GCS endpoint URL.

Useful for testing with emulators. If None, uses the default GCS endpoint.

Default

None (uses default GCS endpoint)

Environment Variables

• OS__STORAGE__TYPE=gcs
• OS__STORAGE__ENDPOINT=http://localhost:9000 (optional)

bucket: String

GCS bucket name.

The bucket must exist before starting the server.

Environment Variables

• OS__STORAGE__BUCKET=my-gcs-bucket

tcp_user_timeout: Duration

Maximum time TCP data may remain unacknowledged or blocked before failing the request.

This detects stalled transports. It does not limit the total upload duration or the time waiting for a response after the upload is acknowledged. Applied on Linux and ignored on other platforms. 0s uses the operating system’s default.

Default

30s

Environment Variables

• OS__STORAGE__TCP_USER_TIMEOUT=30s

cogs: Option<CostTrackerStreamConfig>

Reports what this backend stores, for per-usecase cost attribution.

Default

None, which disables reporting for this backend.

Environment Variables

• OS__STORAGE__COGS__SHARED_RESOURCE_ID=gcs_objectstore
• OS__STORAGE__COGS__SAMPLE_RATE=1.0 (optional)
