An error decoding SCALE bytes.

Variants

BitSequenceError(FromMetadataError)

We ran into an error trying to decode a bit sequence.

CannotDecodeCompactIntoType(Type<PortableForm>)

The type we’re trying to decode is supposed to be compact encoded, but that is not possible.

InvalidStr(Utf8Error)

Failure to decode bytes into a string.

InvalidChar(u32)

We could not convert the u32 that we found into a valid char.

NotEnoughInput

We expected more bytes to finish decoding, but could not find them.

VariantNotFound(u8, TypeDefVariant<PortableForm>)

We found a variant that does not match with any in the type we’re trying to decode from.

CodecError(Error)

Some error emitted from a codec::Decode impl.

TypeIdNotFound(u32)

We could not find the type given in the type registry provided.

Unexpected(Unexpected)

This is returned by default if a visitor function is not implemented.

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> DecodeError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Error for DecodeError

fn source(&self) -> Option<&(dyn Error + 'static)>

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<DecodeError> for Error

fn from(err: DecodeError) -> Error

Converts to this type from the input type.

impl From<DecodeError> for ErrorKind

fn from(original: DecodeError) -> ErrorKind

Converts to this type from the input type.

impl From<Error> for DecodeError

fn from(original: Error) -> DecodeError

Converts to this type from the input type.

impl From<FromMetadataError> for DecodeError

fn from(original: FromMetadataError) -> DecodeError

Converts to this type from the input type.

impl From<Utf8Error> for DecodeError

fn from(original: Utf8Error) -> DecodeError

Converts to this type from the input type.

impl PartialEq for DecodeError

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

This method tests for self and other values to be equal, and is used by ==.

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

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