I'm trying the build a generic currying function that's look like:
package curry
import (
"fmt"
"reflect"
)
// Function
type fn interface{}
// Function parameter
type pr interface{}
// It return the curried function
func It(f fn, p ...pr) (fn, error) {
// examine the concret type of the function f
if reflect.ValueOf(f).Kind() == reflect.Func {
// Get the slice of input and output parameters type
} else {
return nil, fmt.Errorf("%s", "takes a function as a first parameter")
}
// _, _ = f, p
return nil, nil
}
Is it possible to extract the slice of input and output parameters types as []reflect.Type
of the function f
?
