Failure while decoding a value from bytes.

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.

UnexpectedEof

The input ended before the value was complete.

Fields

needed: usize

How many more bytes the reader wanted (at least).

VarIntTooLong

A VarInt was longer than 5 bytes (or a VarLong longer than 10).

NegativeLength(i64)

A length prefix was negative.

LengthTooLarge

A length prefix was larger than the remaining input or a configured limit.

Fields

len: usize

The declared length.

limit: usize

The limit it exceeded.

InvalidUtf8

A string was not valid UTF-8 (or NBT Modified UTF-8).

InvalidNbtTag(u8)

An NBT tag id was not a known tag type.

NbtTooDeep(usize)

NBT nested deeper than the allowed limit.

NbtEndList

An NBT list declared elements of type End with a non-zero length.

Invalid(&'static str)

A value that is not allowed by the format (e.g. an empty top-bit-terminated array).

TrailingBytes(usize)

Bytes were left over after a packet body was decoded.

UnknownPacketId(i32)

The packet id is not known for this state/direction/version.

IdMismatch

A typed decode was requested for a packet with a different id.

Fields

expected: i32

Id of the requested packet type.

actual: i32

Id of the raw packet.

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> Self

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Eq for DecodeError

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<DecodeError> for FrameError

fn from(source: DecodeError) -> Self

Converts to this type from the input type.

impl PartialEq for DecodeError

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

Equality operator ==.

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

Inequality operator !=.
