Basic implementation of block-authoring logic.
|
|
|
|
# Example
|
|
|
|
```rust
|
|
// The first step is to create a `ProposerFactory`.
|
|
let mut proposer_factory = ProposerFactory::new(client.clone(), txpool.clone(), None);
|
|
|
|
// From this factory, we create a `Proposer`.
|
|
let proposer = proposer_factory.init(
|
|
&client.header(client.chain_info().genesis_hash).unwrap().unwrap(),
|
|
);
|
|
|
|
// The proposer is created asynchronously.
|
|
let 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),
|
|
);
|
|
|
|
// We wait until the proposition is performed.
|
|
let block = futures::executor::block_on(future).unwrap();
|
|
println!("Generated block: {:?}", block.block);
|
|
```
