A schema for the opts that a tracer accepts.

Opts

• adapter(:atom) Required: The third party adapter to use
• disabled?(:boolean): Allows for wholesale disabling a tracer - Default: false
• strategy(:atom): The storage and tracing strategy. Currently only supports local process dictionary. - Default: Spandex.Strategy.Pdict
• sender(:atom): Once a trace is complete, it is sent using this module. Defaults to the default_sender/0 of the selected adapter
• tracer(:atom): Don’t set manually. This option is passed automatically.

Span Creation

• service(:atom) Required: The default service name to use for spans declared without a service
• env(:string): A name used to identify the environment name, e.g prod or development - Default: “unknown”
• services([{:keyword, :atom}, :keyword]): A mapping of service name to the default span types. For instance datadog knows about :db, :cache and :web - Default: []
• id(:any)
• trace_id(:any)
• name(:string)
• http([:keyword, {:struct, Spandex.Span.Http}])
• error([:keyword, {:struct, Spandex.Span.Error}])
• completion_time(:any)
• parent_id(:any)
• resource([:atom, :string])
• sql_query([:keyword, {:struct, Spandex.Span.SqlQuery}])
• start(:any)
• type(:atom)
• tags(:keyword) - Default: []

All tracer functions that take opts use this schema. This also accepts defaults for any value that can be given to a span.
