pub struct EngineHandler<T, S, D> { /* private fields */ }
Expand description
A ChainHandler
that advances the chain based on incoming requests (CL engine API).
This is a general purpose request handler with network access. This type listens for incoming messages and processes them via the configured request handler.
§Overview
This type is an orchestrator for incoming messages and responsible for delegating requests received from the CL to the handler.
It is responsible for handling the following:
- Delegating incoming requests to the
EngineRequestHandler
. - Advancing the
EngineRequestHandler
by polling it and emitting events. - Downloading blocks on demand from the network if requested by the
EngineApiRequestHandler
.
The core logic is part of the EngineRequestHandler
, which is responsible for processing the
incoming requests.

impl<T, S, D> EngineHandler<T, S, D>
Sourcepub const fn new(handler: T, downloader: D, incoming_requests: S) -> Selfwhere
T: EngineRequestHandler,
pub const fn new(handler: T, downloader: D, incoming_requests: S) -> Selfwhere
T: EngineRequestHandler,
Creates a new EngineHandler
with the given handler and downloader and incoming stream of
requests.
Sourcepub fn handler_mut(&mut self) -> &mut T
pub fn handler_mut(&mut self) -> &mut T
Returns a mutable reference to the request handler.
