An error that occurred when decoding.

Variants

BufferLength

Not enough data was provided in the input.

Fields

for_type: &'static str

expected: usize

given: usize

InvalidLen

Length did not match the statically expected length.

Fields

expected: usize

given: usize

InvalidTag

The tag does not exist for the sum.

Fields

tag: u8

sum_name: Option<String>

InvalidUtf8

Expected data to be UTF-8 but it wasn’t.

InvalidBool(u8)

Expected the byte to be 0 or 1 to be a valid bool.

Other(String)

Custom error not in the other variants of DecodeError.

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> DecodeError

Returns a duplicate 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, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Error for DecodeError

fn custom(msg: impl Display) -> DecodeError

Raised when there is general error when deserializing a type.

fn unknown_variant_tag<'de, T>(tag: u8, expected: &T) -> DecodeError

where T: SumVisitor<'de>,

The tag does not specify a variant of the sum type.

fn invalid_product_length<'de, T>(len: usize, expected: &T) -> Self

where T: ProductVisitor<'de>,

The product length was not as promised.

fn missing_field<'de, T>( index: usize, field_name: Option<&str>, prod: &T, ) -> Self

where T: ProductVisitor<'de>,

There was a missing field at index.

fn duplicate_field<'de, T>( index: usize, field_name: Option<&str>, prod: &T, ) -> Self

where T: ProductVisitor<'de>,

A field with index was specified more than once.

fn unknown_field_name<'de, T>(field_name: &str, expected: &T) -> Self

where T: FieldNameVisitor<'de>,

A field with name field_name does not exist.

fn unknown_variant_name<'de, T>(name: &str, expected: &T) -> Self

where T: VariantVisitor<'de>,

The name is not that of a variant of the sum type.

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<Utf8Error> for DecodeError

fn from(_: Utf8Error) -> DecodeError

Converts to this type from the input type.

impl PartialEq for DecodeError

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