Struct sp_blockchain::TreeRoute [−][src]
pub struct TreeRoute<Block: BlockT> { /* fields omitted */ }
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]
<- R3 <- R2 <- R1
/
C
\-> E1 -> E2
Tree route from C to E2. Retracted empty. Common is C, enacted [E1, E2]
C -> E1 -> E2
Implementations
Get a slice of all retracted blocks in reverse order (towards common ancestor).
Convert into all retracted blocks in reverse order (towards common ancestor).
Get the common ancestor block. This might be one of the two blocks of the route.
Get a slice of enacted blocks (descendents of the common ancestor)
