Expand description

Creates a default OpenTelemetryLayer with a Tracer that sends traces to Axiom.

It uses the environment variables AXIOM_TOKEN and optionally AXIOM_URL and AXIOM_DATASET to configure the endpoint. If you want to manually set these or other attributres, use builder() or builder_with_env().

§Errors

Errors if the initialization was unsuccessful, likely because a global subscriber was already installed or AXIOM_TOKEN and/or AXIOM_DATASET is not set or invalid.
