Question 1

How do I make a thread-safe stack in GoSTL?

Accepted Answer

Use stack.New() with the WithGoroutineSafe() option, e.g., s := stack.New[int](stack.WithGoroutineSafe()). This configures the stack for safe concurrent access without additional locking.

Question 2

GoSTL map vs Go native map: which is faster?

Accepted Answer

Go's native hash map is generally faster for lookups, while GoSTL's tree-based map provides ordered iteration. Choose based on whether you need speed or sorted key traversal.

Question 3

Does GoSTL support deletion in bloom filters?

Accepted Answer

No, the bloom filter implementation does not support deletion, as stated in the README. It uses a bitmap for memory efficiency but has inherent error rates and this limitation.

Question 4

How to sort a vector in descending order with GoSTL?

Accepted Answer

Wrap the vector with iterators and use sort.Sort() with a reverse comparator. Example: sort.Sort[int](v.Begin(), v.End(), comparator.Reverse(comparator.IntComparator)) from the provided examples.

Question 5

Is GoSTL good for educational purposes?

Accepted Answer

Yes, its wide range of classic data structures and algorithms makes it useful for learning, but the complexity might overwhelm beginners compared to simpler Go tutorials.

Question 6

What are the error rates for GoSTL bloom filters?

Accepted Answer

The error rate isn't specified in the README; it depends on configuration (e.g., hash functions). Bloom filters trade accuracy for memory savings, and deletion is unsupported.

Question 7

How to iterate over a set in GoSTL?

Accepted Answer

Use the iterator API: for iter := set.Begin(); iter.IsValid(); iter.Next() { access iter.Value() }. This pattern is consistent across containers like sets and maps.
