Enum DecodingError

#[non_exhaustive]
pub enum DecodingError {
    UnexpectedEnd {
        extra_len: usize,
    },
    UnexpectedVariant {
        type_name: &'static str,
        found_byte: u8,
    },
    Str(Utf8Error),
    IntegerOverflow,
    DateTime,
}

Errors that can be occurred by decoding a type.

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.

UnexpectedEnd

The source reached its end but more bytes were expected.

Fields

extra_len: usize

How many extra bytes are needed.

UnexpectedVariant

Invalid variant was found. This error is generally for enums.

Fields

type_name: &'static str

The type name that was being decoded.

found_byte: u8

The byte that has been read.

Str(Utf8Error)

Which can be occurred when attempting to decode bytes as a str, it is essentially an UTF-8 error.

IntegerOverflow

The encoded varint is outside of the range of the target integral type.

This may happen if an usize was encoded on 64-bit architecture and then decoded on 32-bit architecture (from large type to small type).

DateTime

Which can be occurred on out-of-range number of seconds and/or invalid nanosecond.

Trait Implementations

impl Clone for DecodingError

fn clone(&self) -> DecodingError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DecodingError

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

Formats the value using the given formatter.

impl Display for DecodingError

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

Formats the value using the given formatter.

impl Error for DecodingError

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 DecodingError

fn from(source: Utf8Error) -> Self

Converts to this type from the input type.
