Struct FinalityNotification

pub struct FinalityNotification<Block: BlockT> {
    pub hash: Block::Hash,
    pub header: Block::Header,
    pub tree_route: Arc<[Block::Hash]>,
    pub stale_heads: Arc<[Block::Hash]>,
    /* private fields */
}

Summary of a finalized block.

Fields

hash: Block::Hash

Finalized block header hash.

header: Block::Header

Finalized block header.

tree_route: Arc<[Block::Hash]>

Path from the old finalized to new finalized parent (implicitly finalized blocks).

This maps to the range (old_finalized, new_finalized).

stale_heads: Arc<[Block::Hash]>

Stale branches heads.

Implementations

impl<Block: BlockT> FinalityNotification<Block>

pub fn from_summary( summary: FinalizeSummary<Block>, unpin_worker_sender: TracingUnboundedSender<UnpinWorkerMessage<Block>>, ) -> FinalityNotification<Block>

Create finality notification from finality summary.

pub fn into_unpin_handle(self) -> UnpinHandle<Block>

Consume this notification and extract the unpin handle.

Note: Only use this if you want to keep the block pinned in the backend.
