Module sc_consensus::import_queue

Expand description

Import Queue primitive: something which can verify and import blocks.

This serves as an intermediate and abstracted step between synchronization and import. Each mode of consensus will have its own requirements for block verification. Some algorithms can verify in parallel, while others only sequentially.

The ImportQueue trait allows such verification strategies to be instantiated. The BasicQueue and BasicVerifier traits allow serial queues to be instantiated simply.

Modules

Provides the buffered_link utility.

Structs

Interface to a basic block import queue that is importing blocks sequentially in a separate task, with plugable verification.

Block data used by the queue.

Enums

BlockImportError

Block import error.

BlockImportStatus

Block import successful result.

Traits

ImportQueueService

Blocks import queue API.

Hooks that the verification queue can use to influence the synchronization algorithm.

Verify a justification of a block

Functions

import_single_block

Single block import function.

Type Definitions

Shared block import struct used by the queue.

BoxJustificationImport

Shared justification import struct used by the queue.

DefaultImportQueue

A commonly-used Import Queue type.
