What did you do?

I've been trying to work with the github.com/apple/foundationdb/bindings/go/src/fdb package that I loaded from Go modules

All I've done was get the package from go modules

go get github.com/apple/foundationdb/bindings/[email protected]

Then using a simple program tried to use it

package main

import (
	"fmt"
	"log"

	"github.com/apple/foundationdb/bindings/go/src/fdb"
)

func main() {
	fdb.MustAPIVersion(730)

	// Open the default database
	db, err := fdb.MustOpenDefault()
	if err != nil {
		log.Fatalf("Failed to open database: %v", err)
	}

	// Create keys for our test
	nameKey := []byte("person:name")
	ageKey := []byte("person:age")

	// Write some data in a transaction
	_, err = db.Transact(func(tr fdb.Transaction) (interface{}, error) {
		fmt.Println("Setting values...")
		tr.Set(nameKey, []byte("John Smith"))
		tr.Set(ageKey, []byte("42"))
		return nil, nil
	})
	if err != nil {
		log.Fatalf("Transaction failed: %v", err)
	}

	// Read data in a transaction
	result, err := db.Transact(func(tr fdb.Transaction) (interface{}, error) {
		fmt.Println("Reading values...")

		// Future represents a value that may not be ready yet
		nameFuture := tr.Get(nameKey)
		ageFuture := tr.Get(ageKey)

		// Wait for the futures to be ready and get their values
		name := nameFuture.MustGet()
		age := ageFuture.MustGet()

		// Return the results
		return map[string][]byte{
			"name": name,
			"age":  age,
		}, nil
	})
	if err != nil {
		log.Fatalf("Read transaction failed: %v", err)
	}

	// Type assertion to get our result map
	data := result.(map[string][]byte)

	// Print the results
	fmt.Printf("Name: %s\n", string(data["name"]))
	fmt.Printf("Age: %s\n", string(data["age"]))

	// Clear the data in a transaction
	_, err = db.Transact(func(tr fdb.Transaction) (interface{}, error) {
		fmt.Println("Clearing values...")
		tr.Clear(nameKey)
		tr.Clear(ageKey)
		return nil, nil
	})
	if err != nil {
		log.Fatalf("Clear transaction failed: %v", err)
	}

	fmt.Println("Data successfully written, read and cleared!")
}

What did you see happen?

When I tried to work with the package I noticed that there were a bunch of missing functions from my intellisense and I'd get errors such as undefined: fdb.MustAPIVersion (compiler UndeclaredImportedName)

When I'd go to look at the package in my go module cache <removed>/go/pkg/mod/github.com/apple/foundationdb/bindings/[email protected]/src/fdb/

I can see the missing functions but I have the following errors

No packages found for open file <removed>/go/pkg/mod/github.com/apple/foundationdb/bindings/[email protected]/src/fdb/fdb.go.
This file is ignored by your gopls build. (go list)

What did you expect to see?

I expected gopls to work and show these functions but for some reason it is ignoring them

I have no custom gopls config or build tags selected

Edit:

I found the following issue under the vscode-go project which I added a comment too but it seems to be closed and I don't think has any triage
