%% This record is for the data of a named tracer.
%% The `tracer' contains the modules to use for span creation,
%% the sampler to use at creation time and the processors to
%% run `OnStart' and `OnEnd'.
%% See OpenTelemetry Tracer spec: https://github.com/open-telemetry/opentelemetry-specification/blob/v1.8.0/specification/trace/sdk.md#tracer-creation
