Enum TransactionEnvelopeError 

#[non_exhaustive]
pub enum TransactionEnvelopeError {
    EmptyInput,
    UnsupportedTransactionType {
        type_byte: u8,
    },
    ScalarPrefix {
        prefix: u8,
    },
    ReservedPrefix,
    Decode(DecodeError),
}

Transaction envelope classification failure.

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.

EmptyInput

No bytes were supplied.

UnsupportedTransactionType

The first byte is a typed-prefix value this release does not admit.

The envelope shell intentionally accepts every nonzero typed prefix in 0x01..=0x7f as opaque data. This error is reserved for prefix values outside that admitted shell domain, such as legacy zero if it reaches typed-prefix handling.

Fields

type_byte: u8

Unsupported typed transaction prefix byte.

ScalarPrefix

The first byte is an RLP scalar prefix, not a transaction envelope.

Fields

prefix: u8

Observed scalar prefix byte.

ReservedPrefix

The first byte is the EIP-2718 reserved extension sentinel.

Decode(DecodeError)

The legacy RLP list shell failed exact bounded decoding.

Implementations

impl TransactionEnvelopeError

pub const fn code(self) -> &'static str

Stable machine-readable error code.

pub const fn message(self) -> &'static str

Stable human-readable error message.

pub const fn category(self) -> TransactionEnvelopeErrorCategory

Stable high-level category for policy decisions.

Trait Implementations

impl Clone for TransactionEnvelopeError

fn clone(&self) -> TransactionEnvelopeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TransactionEnvelopeError

impl Debug for TransactionEnvelopeError

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

Formats the value using the given formatter.

impl Display for TransactionEnvelopeError

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

Formats the value using the given formatter.

impl Eq for TransactionEnvelopeError

impl PartialEq for TransactionEnvelopeError

fn eq(&self, other: &TransactionEnvelopeError) -> 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.
