Enum StarkTranscriptFailure 

#[non_exhaustive]
pub enum StarkTranscriptFailure {

A transcript step the proof failed to satisfy.

Variants (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.

MissingPreprocessedCommitment

The described preprocessed-commitment step arrived with no commitment.

Fields

width: usize

Preprocessed column count the run was described with.

UnexpectedPreprocessedCommitment

A preprocessed commitment arrived for a run described without one.

MissingRandomCommitment

The described randomization-commitment step arrived with no commitment.

UnexpectedRandomCommitment

A randomization commitment arrived for a run described without one.

OodPowWitness

The grinding witness did not meet the difficulty its step requires.

Fields

bits: usize

Grinding difficulty the step requires.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
