Beginner in golang.func OutputMe(mainContent []any, dimX, dimY byte, technique string) (message string, e error)
attempt to cross []int{1,2,35} and all the time get an error
can't use []int{…} (worth of kind []int) as []any worth
what am i doing unsuitable?
Oi! Are you able to please format this code? Put the shared code inside an code snippet block, you possibly can simply choose the code and use the </> button
package deal predominant
func predominant() {
// ...code code
}
Please share extra in regards to the code, It’s kinda arduous to grasp what you are attempting to do
was pondering that’s attainable to implement some methodology with []any after which present []integer{1,2,3,4,-6} like an argument
Go has sturdy static typing mannequin and sort []any implies you to make use of precisely this kind, not one other. What you are attempting to do is generic programming, e.g.,
func fn[T []E, E any](sl T) {
// Your code goes right here...
}
However on this case you should assure, that the code in your operate will be capable of deal with any, because it’s each attainable kind. Imho, if you’re not utilizing generics, it’s higher to outline actual kind of the argument.

I feel change ny to simply solely any, so
func OutputMe(mainContent any, dimX, dimY byte, technique string) (message string, e error)
Then if you’re working with []int contained in the operate, you will want to do kind assertion.
Clearly you don’t perceive the information construction, []int is an array of integers, let’s say it’s in a 64-bit system, then every aspect occupies 64 bits, []any, the place any is the pointer, and the pointer occupies 64 bits. Though it appears, each occupy 64 bits, []string and []any, are you able to assure that string takes 64 bits? So []any is just not the identical as any slice. It is best to iterate over []int and stuff it into []any.
go doesnt assist implicit kind conversions between slices. theres no solution to forged []any between different knowledge constructions in go.
additionally, the information construction of []any is an empty interface that shops tips to values of various sorts, whereas []int shops values immediately.
