Struct ExExContext 

Source 
pub struct ExExContext<Node: FullNodeComponents> {
    pub head: BlockNumHash,
    pub config: NodeConfig<<Node::Types as NodeTypes>::ChainSpec>,
    pub reth_config: Config,
    pub events: UnboundedSender<ExExEvent>,
    pub notifications: ExExNotifications<Node::Provider, Node::Evm>,
    pub components: Node,
}
Expand description

Captures the context that an ExEx has access to.

This type wraps various node components that the ExEx has access to.

Fields§

§head: BlockNumHash

The current head of the blockchain at launch.

§config: NodeConfig<<Node::Types as NodeTypes>::ChainSpec>

The config of the node

§reth_config: Config

The loaded node config

§events: UnboundedSender<ExExEvent>

Channel used to send ExExEvents to the rest of the node.

§Important

The exex should emit a FinishedHeight whenever a processed block is safe to prune. Additionally, the exex can preemptively emit a FinishedHeight event to specify what blocks to receive notifications for.

§notifications: ExExNotifications<Node::Provider, Node::Evm>

Channel to receive ExExNotifications.

§Important

Once an ExExNotification is sent over the channel, it is considered delivered by the node.

§components: Node

Node components
