Struct PayloadBuilderService

Source 
pub struct PayloadBuilderService<Gen, St, T>
where
    T: PayloadTypes,
    Gen: PayloadJobGenerator,
    Gen::Job: PayloadJob<PayloadAttributes = T::PayloadBuilderAttributes>,
{ /* private fields */ }
Expand description

A service that manages payload building tasks.

This type is an endless future that manages the building of payloads.

It tracks active payloads and their build jobs that run in a worker pool.

By design, this type relies entirely on the PayloadJobGenerator to create new payloads and does know nothing about how to build them, it just drives their jobs to completion.

Implementations§

Source§

impl<Gen, St, T> PayloadBuilderService<Gen, St, T>
where T: PayloadTypes, Gen: PayloadJobGenerator, Gen::Job: PayloadJob<PayloadAttributes = T::PayloadBuilderAttributes>, <Gen::Job as PayloadJob>::BuiltPayload: Into<T::BuiltPayload>,

Source

pub fn new(generator: Gen, chain_events: St) -> (Self, PayloadBuilderHandle<T>)

Creates a new payload builder service and returns the PayloadBuilderHandle to interact with it.

This also takes a stream of chain events that will be forwarded to the generator to apply additional logic when new state is committed. See also PayloadJobGenerator::on_new_state.

Source

pub fn handle(&self) -> PayloadBuilderHandle<T>

Returns a handle to the service.
