Enum InvalidBlockReason 

Source 
pub enum InvalidBlockReason {
    BadStateRoot,

Expand description

Canonical reason categories for InvalidBlockProof::failure_reason.

Per SPEC §3.4. Adding a new variant is a protocol-version bump — downstream pattern-matches assume exhaustive coverage of exactly these eight cases (see test_dsl_008_all_reasons_enumerated).

The enum is Copy + Hash because it’s a lightweight discriminant that shows up in AppealAdjudicationResult, oracle return values, and metrics labels — passing by value is cheap and avoids .clone() noise in consumers.

Variants§

§

BadStateRoot

Post-block state root doesn’t match the re-executed state.

§

BadParentRoot

Header’s parent hash doesn’t match the canonical parent.

§

BadTimestamp

Timestamp outside allowed window (future or past canonical tip).

§

BadProposerIndex

proposer_index doesn’t match the slot’s assigned proposer.

§

TransactionExecutionFailure

One or more transactions failed during block execution.

§

OverweightBlock

Block exceeds MAX_BLOCK_COST or analogous resource cap.

§

DuplicateTransaction

Block contains the same spend bundle twice.

§

Other

Reason not otherwise categorised; witness should carry detail.
