//! Basic implementation of block-authoring logic.
|
|
//!
|
|
//! # Example
|
|
//!
|
|
//! ```
|
|
//! # use sc_basic_authorship::ProposerFactory;
|
|
//! # use sp_consensus::{Environment, Proposer, RecordProof};
|
|
//! # use sp_runtime::generic::BlockId;
|
|
//! # use std::{sync::Arc, time::Duration};
|
|
//! # use substrate_test_runtime_client::{self, runtime::{Extrinsic, Transfer}, AccountKeyring};
|
|
//! # use sc_transaction_pool::{BasicPool, FullChainApi};
|
|
//! # let client = Arc::new(substrate_test_runtime_client::new());
|
|
//! # let txpool = Arc::new(BasicPool::new(Default::default(), FullChainApi::new(client.clone())));
|
|
//! // The first step is to create a `ProposerFactory`.
|
|
//! let mut proposer_factory = ProposerFactory {
|
|
//! client: client.clone(),
|
|
//! transaction_pool: txpool.clone(),
|
|
//! };
|
|
//!
|
|
//! // From this factory, we create a `Proposer`.
|
|
//! let proposer = proposer_factory.init(
|
|
//! &client.header(&BlockId::number(0)).unwrap().unwrap(),
|
|
//! );
|
|
//!
|
|
//! // The proposer is created asynchronously.
|
|
//! let mut proposer = futures::executor::block_on(proposer).unwrap();
|
|
//!
|
|
//! // This `Proposer` allows us to create a block proposition.
|
|
//! // The proposer will grab transactions from the transaction pool, and put them into the block.
|
|
//! let future = proposer.propose(
|
|
//! Default::default(),
|
|
//! Default::default(),
|
|
//! Duration::from_secs(2),
|
|
//! RecordProof::Yes,
|
|
//! );
|
|
//!
|
|
//! // We wait until the proposition is performed.
|
|
//! let block = futures::executor::block_on(future).unwrap();
|
|
//! println!("Generated block: {:?}", block.block);
|
|
//! ```
