Enum TranscriptError 

pub enum TranscriptError {
    MissingBegin(Box<MissingBeginInfo>),
    InvalidKind(Box<InvalidKindInfo>),
    MismatchedBeginEnd(Box<MismatchedBeginEndInfo>),
    MissingEnd(Box<MissingEndInfo>),
    BadProofShape {
        reason: &'static str,
    },
}

Failures that can arise while validating a pattern or reading a proof.

Every variant is reachable.

Divergence between the recorded pattern and the code replaying it is a programming bug, not malformed input, so it panics with a diff instead of landing here.

Variants

MissingBegin(Box<MissingBeginInfo>)

An end marker was found with no matching opener in the sequence.

InvalidKind(Box<InvalidKindInfo>)

A nested step uses a kind incompatible with the surrounding sub-protocol.

MismatchedBeginEnd(Box<MismatchedBeginEndInfo>)

A closer does not match the most recent opener.

MissingEnd(Box<MissingEndInfo>)

An opener was never closed before the sequence ended.

BadProofShape

Verifier-side parsing of the prover’s serialized output failed.

Fields

reason: &'static str

Short reason describing the parse failure.

Trait Implementations

impl Clone for TranscriptError

fn clone(&self) -> Self

impl Eq for TranscriptError

impl Error for TranscriptError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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.

impl PartialEq for TranscriptError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
