KleisliTrace

trace4cats.Trace$.KleisliTrace
class KleisliTrace[F[_]] extends WithContext[[_] =>> Kleisli[F, Span[F], _$11]]

A trace instance for Kleisli[F, Span[F], *], which is the mechanism we use to introduce context into our computations. We can also "lensMap" out to Kleisli[F, E, *] given a lens from E to Span[F].

Convert the span context into headers may be propagated outside of the application

Value parameters

toHeaders

ToHeaders implementation. Converts span context to headers that may be propagated outside of the application. Defaults to ToHeaders.standard, which is a collection of headers that conform to open standards. Other header implementations that do not conform to open standards are supported. See ToHeaders for details or use ToHeaders.all
