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, APP_NAME
• Service version: OTEL_SERVICE_VERSION, SERVICE_VERSION, APP_VERSION

Implementations

impl DetectResource

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

service.name is first extracted from environment variables (in this order) OTEL_SERVICE_NAME, SERVICE_NAME, APP_NAME. But a default value can be provided with this method.

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.
