| 9 | Returns the number of elements of an array or struct, the number of |
| 10 | characters in a string, number of bytes in a byte sequence, or the |
| 11 | number of keys in a mapping. |

| Zesstra | 715ec20 | 2025-07-09 22:18:31 +0200 | [diff] [blame] | 13 | As a special case, the number 0 can be passed, and the function |
| 14 | will return 0. |

| Zesstra | 715ec20 | 2025-07-09 22:18:31 +0200 | [diff] [blame] | 16 | If there were any objects destroyed in the game since the mapping was |
| 17 | last checked for destructed keys, the mapping() needs to be checked |
| 18 | for destructed objects in keys first. In that case, the runtime |
| 19 | increases linear with the number of keys in the mapping (O(n)). |
| 20 | Otherwise the runtime is independent of the mappings size (O(1)). |
