Question

Is there can convert the stuff read from input port to some specific type in Racket? like turning the stuff read from piped port into a defined struct? if not, then how can process communication resume those data types passed back and forth?

Answer 1

Read about the racket/serialize library in the guide and also see the #:prefab option for struct that can create struct types that can always be read with read — it’s also described in the chapter on structs in the guide.
