All errors that can occur during parsing.

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.

UnexpectedEof

Input ended before the structure was complete.

Fields

needed: usize

How many bytes were needed.

available: usize

How many were available.

InvalidVarInt

A variable-length integer had an invalid encoding.

IntegerTooLarge

A length/value was valid as a u64 but does not fit into the platform usize.

Fields

value: u64

The original integer value that could not fit into usize.

OversizedData

A script or data field exceeded the allowed maximum size.

Fields

size: usize

Actual size that was encountered.

max: usize

Maximum size allowed by the parser.

UnsupportedVersion(i32)

The block / transaction version is not supported by this parser.

MagicMismatch

The magic bytes at the start of a raw block did not match.

Fields

expected: [u8; 4]

The magic bytes this parser was configured to expect.

got: [u8; 4]

The magic bytes that were actually found in the input.

InvalidSegwitFlag(u8)

Segwit marker / flag bytes are invalid.

Tuple Fields

0: u8

The invalid flag byte.

InvalidInputCount

Transaction input count was invalid (e.g., zero in legacy format).

TrailingBytes

Extra bytes remained after parsing a structure in strict mode.

Fields

remaining: usize

Number of bytes left unread.

IncompleteTransactions

Not all transactions declared in the block were parsed.

Fields

expected: usize

Number of transactions declared in the block header.

parsed: usize

Number of transactions that were actually parsed.

InvalidCoinbase

Coinbase transaction had a non-empty txid reference (must be all-zero).

InvalidCoinbaseCount

A block contained an unexpected number of coinbase transactions.

Fields

count: usize

Number of coinbase transactions observed while parsing.

Io

An underlying I/O error occurred (only available with the std feature).

Fields

message: String

Human-readable I/O error message.

Trait Implementations

impl Clone for ParseError

fn clone(&self) -> ParseError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

Available on crate feature std only.

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 ParseError

Available on crate feature std only.

fn from(e: Error) -> Self

Converts to this type from the input type.

impl PartialEq for ParseError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
