@ned14 This is by design; if a call to resize() makes it larger, what should the new node elements be initialized as? Integers with value 0? Empty strings? There isn't really a logical choice here; since more than one is reasonable, that implicitly means that none of them are.

I guess I could provide a resize() operation with a default value, e.g. resize(size_t, string_view) creating strings with the given value if the array needs to grow.

I specifically tried to use it to truncate an overly long array to smaller, and when it wasn't there, that was surprising. I guess .truncate() would do? Otherwise, yes resize with a default value also works, or resize failing if you try to use it for expansion.

Ooh, yes, truncate() is nice and clear, I think. I'll go with that over providing a resize() that's only good for shrinking. I'll also add resize(size_t, <default value>) while I'm at it.

Added in 289c95c:

  • resize(size_t, <default value>)
  • truncate(size_t)
  • max_size(), capacity(), shrink_to_fit() for additional consistency with std::vector
