ValidationInterfaceCallbacks

Swift-friendly wrapper for validation interface callbacks.

final class ValidationInterfaceCallbacks

Overview

Populate the closure properties you care about, then pass to setValidationInterface(_:). The kernel takes ownership of the callback state and releases it when the context is destroyed.

All callbacks are dispatched on kernel-internal threads and block further validation while executing — keep handlers fast.

Initializers

init(blockChecked: ((Block, BlockValidationState) -> Void)?, powValidBlock: ((Block, BlockTreeEntrySnapshot) -> Void)?, blockConnected: ((Block, BlockTreeEntrySnapshot) -> Void)?, blockDisconnected: ((Block, BlockTreeEntrySnapshot) -> Void)?)
Creates validation interface callbacks.

Instance Properties

let blockChecked: ((Block, BlockValidationState) -> Void)?
Called when a new block has been fully validated.
let blockConnected: ((Block, BlockTreeEntrySnapshot) -> Void)?
Called when a valid block has been connected to the best chain.
let blockDisconnected: ((Block, BlockTreeEntrySnapshot) -> Void)?
Called during a re-org when a block has been removed from the best chain.
let powValidBlock: ((Block, BlockTreeEntrySnapshot) -> Void)?
Called when a new block extends the header chain with valid PoW.
