A decode error.

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.

Short

The buffer ran out mid-value. Retry once more bytes arrive.

Long

The value claims more bytes than the enclosing message allows.

InvalidString(FromUtf8Error)

A string field was not valid UTF-8.

InvalidMessage(u64)

The message type ID is unknown for the negotiated version.

InvalidSubscribeLocation

A SUBSCRIBE start/end location is malformed or out of order.

InvalidValue

A field held a value outside its permitted range.

TooMany

A repeated field exceeded the count this implementation accepts.

BoundsExceeded

An integer was too large for the QUIC varint range.

ExpectedEnd

More data followed where the message was required to end.

ExpectedData

The stream ended where a payload was required.

Duplicate

A parameter or field appeared more than once.

Missing

A required parameter or field was absent.

Unsupported

The value is well-formed but this implementation does not handle it.

TrailingBytes

Bytes remained after the value was fully decoded.

Version

The field does not exist in the negotiated protocol version.

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

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 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 Error

fn from(source: DecodeError) -> Self

Converts to this type from the input type.

impl From<FromUtf8Error> for DecodeError

fn from(source: FromUtf8Error) -> Self

Converts to this type from the input type.

impl From<TooManyOrigins> for DecodeError

fn from(_: TooManyOrigins) -> Self

Converts to this type from the input type.
