Enum CanonStateNotification 

pub enum CanonStateNotification<N = EthPrimitives>
where
    N: NodePrimitives,
{
    Commit {
        new: Arc<Chain<N>>,
    },
    Reorg {
        old: Arc<Chain<N>>,
        new: Arc<Chain<N>>,
    },
}
Expand description

A notification that is sent when a new block is imported, or an old block is reverted.

The notification contains at least one Chain with the imported segment. If some blocks were reverted (e.g. during a reorg), the old chain is also returned.

Variants§

§

Commit

The canonical chain was extended.

Fields

§new: Arc<Chain<N>>

The newly added chain segment.

§

Reorg

A chain segment was reverted or reorged.

  • In the case of a reorg, the reverted blocks are present in old, and the new blocks are present in new.
  • In the case of a revert, the reverted blocks are present in old, and new is an empty chain segment.

Fields

§old: Arc<Chain<N>>

The chain segment that was reverted.

§new: Arc<Chain<N>>

The chain segment that was added on top of the canonical chain, minus the reverted blocks.

In the case of a revert, not a reorg, this chain segment is empty.

Implementations§

§

impl<N> CanonStateNotification<N>
where N: NodePrimitives,

pub fn reverted(&self) -> Option<Arc<Chain<N>>>

Get the chain segment that was reverted, if any.

pub fn committed(&self) -> Arc<Chain<N>>

Get the newly imported chain segment, if any.

pub fn tip(&self) -> &RecoveredBlock<<N as NodePrimitives>::Block>

Get the new tip of the chain.

Returns the new tip for Self::Reorg and Self::Commit variants which commit at least 1 new block.

pub fn block_receipts( &self, ) -> Vec<(BlockReceipts<<N as NodePrimitives>::Receipt>, bool)>
where <N as NodePrimitives>::SignedTx: Encodable2718,

Get receipts in the reverted and newly imported chain segments with their corresponding block numbers and transaction hashes.

The boolean in the tuple (2nd element) denotes whether the receipt was from the reverted chain segment.
