    InvalidMagic {
        found: [u8; 8],
    },
    UnsupportedVersion {
        version: u32,

}

Errors that can occur while replaying a proof log.

Variants

Io(Error)

Underlying I/O failure.

InvalidMagic

File did not begin with the expected magic bytes.

Fields

found: [u8; 8]

Bytes that were actually read.

UnsupportedVersion

The log file was written by an incompatible format version.

Fields

version: u32

Version found in the file.

UnknownKind(u8)

An unknown record kind byte was encountered.

ForwardReference

A premise ID referenced a node that has not been seen yet.

Fields

referencing: u32

Node that contains the invalid reference.

missing: u32

Node ID that has not been defined yet.

InvalidUtf8(String)

A byte slice could not be decoded as UTF-8.

EmptyLog

The replay produced zero steps (empty or truncated file).

FieldTooLarge(u32)

A length-prefixed field had an unreasonably large value (guards OOM).

Trait Implementations

impl Debug for ProofError

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

Formats the value using the given formatter.

impl Display for ProofError

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

Formats the value using the given formatter.

impl Error for ProofError

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 ProofError

fn from(source: Error) -> Self

Converts to this type from the input type.
