Enum zvariant::Error

#[non_exhaustive]
pub enum Error {
    Message(String),
    Io(Error),
    IncorrectType,
    Utf8(Utf8Error),
    PaddingNot0(u8),
    UnknownFd,
    MissingFramingOffset,
    IncompatibleFormat(Signature<'static>, EncodingFormat),
    Infallible,
}

Error type used by zvariant API.

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.

Message

Generic error. All serde errors gets transformed into this variant.

Tuple Fields of Message

0: String

Io

Wrapper for std::io::Error

Tuple Fields of Io

0: Error

IncorrectType

Type conversions errors.

Utf8

Wrapper for std::str::Utf8Error

Tuple Fields of Utf8

0: Utf8Error

PaddingNot0

Non-0 padding byte(s) encountered.

Tuple Fields of PaddingNot0

0: u8

UnknownFd

The deserialized file descriptor is not in the given FD index.

MissingFramingOffset

Missing framing offset at the end of a GVariant-encoded container,

IncompatibleFormat

The type (signature as first argument) being (de)serialized is not supported by the format.

Tuple Fields of IncompatibleFormat

0: Signature<'static>1: EncodingFormat

Infallible

👎 Deprecated

Only exists to allow TryFrom<T> for T conversions. You should never actually be getting this error from any API.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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

impl Error for Error

fn custom<T>(msg: T) -> Error where
    T: Display, 

Used when a Serialize implementation encounters any error while serializing a type.

impl Error for Error

fn custom<T>(msg: T) -> Error where
    T: Display, 

Raised when there is general error when deserializing a type.

fn invalid_type(unexp: Unexpected<'_>, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a type different from what it was expecting.

fn invalid_value(unexp: Unexpected<'_>, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a value of the right type but that is wrong for some other reason.

fn invalid_length(len: usize, exp: &dyn Expected) -> Self

Raised when deserializing a sequence or map and the input data contains too many or too few elements.

fn unknown_variant(variant: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize enum type received a variant with an unrecognized name.

fn unknown_field(field: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize struct type received a field with an unrecognized name.

fn missing_field(field: &'static str) -> Self

Raised when a Deserialize struct type expected to receive a required field with a particular name but that field was not present in the input.

fn duplicate_field(field: &'static str) -> Self

Raised when a Deserialize struct type received more than one of the same field.

impl From<Infallible> for Error

fn from(i: Infallible) -> Self

Performs the conversion.

impl PartialEq<Error> for Error

fn eq(&self, other: &Self) -> 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 !=.
