Would check now |
Yes, please @rjl493456442 push it to the branch, it loosk good and has a clean structure, try to test as well or I could do it for you |
- Remove separate prefixIterator type per reviewer feedback - Add prefix and stop fields directly to nodeIterator - Implement proper subtree boundaries with both start and stop points - Simplify maintenance by avoiding unnecessary new types Co-authored-by: gballet <[email protected]>

NodeIteratorWithPrefix()method to support iterating only nodes within a specific key prefixNodeIteratorWithRange()method to support iterating only nodes within a specific key rangeCurrent
NodeIteratoralways traverses the entire remaining trie from a start position.For non-ethereum applications using the trie implementation, there's no way to limit
iteration to just a subtree with a specific prefix.
Usage:
Testing: Comprehensive test suite covering edge cases and boundary conditions.
Closes #32484
