Chain chains together a series of middleware.

Funcs constructs a Middleware from a pair of functions, one for preprocessing, one for postprocessing.

LogMisconfiguration logs a misconfiguration for the RPC.

Postprocess creates a middleware from a function that does postprocessing only.

Preprocess creates a middleware from a function that does pre-processing only.

WithLogger returns logging middleware that provides a per-rpc logger with some initial fields set.

WithMetrics adds per-call metrics to each RPC call.
