QUESTION

How can I instantiate a new pointer of type argument with generic Go?

Asked 2022-Mar-18 at 20:27

Now that type parameters are available on golang/go:master, I decided to give it a try. It seems that I'm running into a limitation I could not find in the Type Parameters Proposal. (Or I must have missed it).

I want to write a function which returns a slice of values of a generic type with the constraint of an interface type. If the passed type is an implementation with a pointer receiver, how can we instantiate it?

Edit: see blackgreen's answer, which I also found later on my own while scanning through the same documentation they linked. I was going to edit this answer to update based on that, but now I don't have to. :-)

There is probably a better way—this one seems a bit clumsy—but I was able to work around this with reflect:

The language specifications explicitly disallow using interfaces with type elements as anything other than type parameter constraints (the quote is under the paragraph Interface types):

Interfaces that are not basic may only be used as type constraints, or as elements of other interfaces used as constraints. They cannot be the types of values or variables, or components of other, non-interface types.

An interface that embeds comparable or another non-basic interface is also non-basic. Your Number interface contains a union, hence it is non-basic too.

A few examples:

Ensure your VSCode uses the arm64 version. (it can use a different go version from the system)
Run Go: install/update tools. It will rebuild all tools with the arm64 go version.

Go Generics - Unions

Asked 2022-Feb-20 at 19:49

I'm playing around with go generics by modifying a library I created for working with slices. I have a Difference function which accepts slices and returns a list of unique elements only found in one of the slices.

I modified the function to use generics and I'm trying to write unit tests with different types (e.g. strings and ints) but am having trouble with the union type. Here's what I have, now:

ANSWER

Answered 2021-Oct-29 at 19:33

I've passed your code through gotip that uses a more evolved implementation of the proposal and it does not complain about that part of the code, so I would assume that the problem is with the go2go initial implementation.

Please note that your implementation will not work since you can definitely use parametric interfaces in type assertion expressions, but you can't use interfaces with type lists as you are doing in testDifference[intOrString]

Why doesn't dereferencing a nil pointer in unsafe.Sizeof() cause a panic?

...

ANSWER

Answered 2022-Feb-10 at 10:08

Spec: Package unsafe:

Calls to Alignof, Offsetof, and Sizeof are compile-time constant expressions of type uintptr.

These functions are evaluated at compile time, no actual dereferencing happens at runtime.

This is possible because the pointed value is not needed, only information about its type is needed, which does not need dereferencing.

It's also documented at unsafe.Sizeof():

The return value of Sizeof is a Go constant.

Constants in Go are compile-time constants.

Also see Spec: Constants:

A constant value is represented by a rune, integer, floating-point, imaginary, or string literal, an identifier denoting a constant, a constant expression, a conversion with a result that is a constant, or the result value of some built-in functions such as unsafe.Sizeof applied to any value, cap or len applied to some expressions, real and imag applied to a complex constant and complex applied to numeric constants.

See similar examples (which without passing them to unsafe.Sizeof() would panic at runtime or block indefinitely, but they work just fine):

Since you're already using Docker, I'd suggest using a multi-stage build. Using a standard docker image like golang one can build an executable asset which is guaranteed to work with other docker linux images:
