Enum BlockHeaderDecodeError 

#[non_exhaustive]
pub enum BlockHeaderDecodeError {
    Decode(DecodeError),
    WrongFieldCount {
        expected: usize,
        found: usize,
    },

Execution header decode 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.

Decode(DecodeError)

Header RLP list decode failed.

WrongFieldCount

Header field count did not match the selected fork field set.

Fields

expected: usize

Expected field count.

found: usize

Actual field count.

FieldDecode

A field failed RLP or primitive-domain decoding.

Fields

field: BlockHeaderField

Field being decoded.

source: DecodeError

Underlying decode error.

InvalidFieldLength

A fixed-width field had the wrong byte length.

Fields

field: BlockHeaderField

Field being decoded.

expected: usize

Expected byte length.

found: usize

Actual decoded scalar byte length.

Implementations

impl BlockHeaderDecodeError

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

Trait Implementations

impl Clone for BlockHeaderDecodeError

fn clone(&self) -> BlockHeaderDecodeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BlockHeaderDecodeError

impl Debug for BlockHeaderDecodeError

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

Formats the value using the given formatter.

impl Display for BlockHeaderDecodeError

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

Formats the value using the given formatter.

impl Eq for BlockHeaderDecodeError

impl PartialEq for BlockHeaderDecodeError

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