Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

InvalidIndex

returned if the supplied row or col in (row,col,val) tuple is out of range

§

InvalidStepCircuitIO

returned if the step circuit calls inputize or alloc_io in its synthesize method instead of passing output with the return value

§

InvalidInputLength

returned if the supplied input is not of the right length

§

InvalidWitnessLength

returned if the supplied witness is not of the right length

§

UnSat

returned if the supplied witness is not a satisfying witness to a given shape and instance

§

DecompressionError

returned when the supplied compressed commitment cannot be decompressed

§

ProofVerifyError

returned if proof verification fails

§

InvalidCommitmentKeyLength

returned if the provided commitment key is not of sufficient length

§

InvalidNumSteps

returned if the provided number of steps is zero

§

InvalidPCS

returned when an invalid PCS evaluation argument is provided

§

InvalidSumcheckProof

returned when an invalid sum-check proof is provided

§

InvalidInitialInputLength

returned when the initial input to an incremental computation differs from a previously declared arity

§

InvalidStepOutputLength

returned when the step execution produces an output whose length differs from a previously declared arity

§

InternalTranscriptError

returned when the transcript engine encounters an overflow of the round number

§

InvalidMultisetProof

returned when the multiset check fails

§

InvalidProductProof

returned when the product proof check fails

§

returned when the consistency with public IO and assignment used fails

§

SynthesisError

Fields

§reason: String

The reason for circuit synthesis failure

return when error during synthesis

§

DigestError

returned when there is an error creating a digest

§
