Struct sp_blockchain::TreeRoute
source · [−]pub struct TreeRoute<Block: BlockT> { /* private fields */ }Expand description
A tree-route from one block to another in the chain.
All blocks prior to the pivot in the deque is the reverse-order unique ancestry of the first block, the block at the pivot index is the common ancestor, and all blocks after the pivot is the ancestry of the second block, in order.
The ancestry sets will include the given blocks, and thus the tree-route is never empty.
Tree route from R1 to E2. Retracted is [R1, R2, R3], Common is C, enacted [E1, E2]
