Struct DetectResource

pub struct DetectResource { /* private fields */ }

Resource detection utility for automatically configuring OpenTelemetry service metadata.

This struct helps detect and configure service information from environment variables with fallback values. It supports the standard OpenTelemetry environment variables as well as common service naming conventions.

Environment Variables

The following environment variables are checked in order of priority:

• Service name: OTEL_SERVICE_NAME, service.name from OTEL_RESOURCE_ATTRIBUTES, SERVICE_NAME, APP_NAME
• Service version: OTEL_SERVICE_VERSION, service.version from OTEL_RESOURCE_ATTRIBUTES, SERVICE_VERSION, APP_VERSION

Note: OTEL_RESOURCE_ATTRIBUTES is automatically parsed by the OpenTelemetry SDK’s environment resource detector.

Implementations

impl DetectResource

pub fn new( fallback_service_name: &'static str, fallback_service_version: &'static str, ) -> Self

Creates a new DetectResource with the provided fallback service name and version.

Arguments

• fallback_service_name - The default service name to use if not found in environment variables.
• fallback_service_version - The default service version to use if not found in environment variables.

pub fn build(self) -> Resource

Builds the OpenTelemetry resource with detected service information.

This method checks environment variables in order of priority and falls back to the provided default values if no environment variables are set.

Returns

A configured Resource with service name and version attributes.
