Implementations of this interface can be passed to 22 // the Detect function to generate a Resource from the merged information. 23 // 24 // To load a user defined Resource from the environment variable 25 // OTEL_RESOURCE_ATTRIBUTES the FromEnv Detector can be used. It will interpret 26 // the value as a list of comma delimited key/value pairs 27 // (e.g. `<key1>=<value1>,<key2>=<value2>,...`). 28 // 29 // While this package provides a stable API, 30 // the attributes added by resource detectors may change. 31 package resource // import "go.opentelemetry.io/otel/sdk/resource" 32
