FromSeqPtrOr returns a sequence with the pointer values or the fallback value.
|
|
|
|
```go
|
|
one := 1
|
|
var two *int = nil
|
|
|
|
collection := func(yield func(*int) bool) {
|
|
yield(&one)
|
|
yield(two)
|
|
}
|
|
|
|
values := it.FromSeqPtrOr(collection, 99)
|
|
var result []int
|
|
for val := range values {
|
|
result = append(result, val)
|
|
}
|
|
// result contains [1, 99]
|
|
