Enum VerifyError 

pub enum VerifyError {
    Io(Error),
    InvalidLine {
        line: usize,
        reason: String,
    },
    BrokenChain {
        line: usize,
        expected: String,
        actual: String,
    },
    Empty,
}

Verification failure modes.

Variants

Io(Error)

Underlying I/O error reading the transcript.

InvalidLine

A line did not parse as a [ChainedFact].

Fields

line: usize

1-indexed line number.

reason: String

Parse error.

BrokenChain

The chain is broken: a line’s prev_hash did not match the expected value computed from the previous line.

Fields

line: usize

1-indexed line number where the break was detected.

expected: String

The expected prev_hash (= hash of the previous line).

actual: String

The prev_hash actually recorded on the line.

Empty

The transcript file has zero lines.

Trait Implementations

impl Debug for VerifyError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for VerifyError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for VerifyError

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 From<Error> for VerifyError

fn from(source: Error) -> Self

Converts to this type from the input type.
