Errors returned while decoding proofs.

Variants

BadMagic

File began with invalid magic bytes.

BadVersion

File has a version we do not understand.

BadAttestationTag

Expected an attestation tag but decoded something else.

LEB128Overflow(u32)

Read an LEB128-encoded integer that overflowed the expected size.

BadOpCode(u8)

Encountered an unrecognized opcode.

ExpectedDigestOp(OpCode)

Expected a digest opcode but decoded something else.

OutOfRange

Read a value that is not in the allowed range.

InvalidUriChar

Encountered an invalid character in a URI.

UriTooLong

URI is too long.

RecursionLimit

Recursed deeper than allowed while decoding the proof.

UnexpectedEof

Reached end-of-file unexpectedly.

Io(Error)

General I/O error

Trait Implementations

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Error for DecodeError

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 DecodeError

fn from(err: Error) -> Self

Converts to this type from the input type.
