Enum BlockExecution 

Source 
pub enum BlockExecution {
    StageProposal {
        policy: BundleExecutionPolicy,
    },
    HandleProposal,
    HandleConfirmed {
        oracle_responses: Vec<Vec<OracleResponse>>,
    },
}
Expand description

What a call to ChainStateView::execute_block is doing, carrying exactly the inputs that are legal for that phase.

Bundling the phase together with the replayed oracle responses and the bundle-execution policy makes the illegal combinations unrepresentable: only StageProposal may choose a policy (and thus AutoRetry), and only HandleConfirmed carries oracle responses to replay — so “replay oracle responses while auto-retrying” cannot be constructed.

Variants§

§

StageProposal

A proposer staging (building) its own block. The bundle-failure policy is caller-chosen (and may be AutoRetry); oracle responses are computed fresh, never replayed.

Fields

§policy: BundleExecutionPolicy

How to handle failing bundles while building the proposal.

§

HandleProposal

A validator validating a received block proposal. Bundles must abort on failure (the proposal is fixed) and oracle responses are computed fresh.

§

HandleConfirmed

A validator executing a confirmed certificate before committing it. Bundles must abort on failure and the certificate’s recorded oracle responses are replayed for determinism.

Fields

§oracle_responses: Vec<Vec<OracleResponse>>

The oracle responses recorded in the certificate, replayed to reproduce the outcome.
