Enum Error

#[non_exhaustive]
pub enum Error {
    Custom(CustomError),
}

Common errors during serde_arrow’s usage

At the moment only a generic string error is supported, but it is planned to offer concrete types to match against.

The error carries a backtrace if RUST_BACKTRACE=1, see std::backtrace for details. This backtrace is included when printing the error. If the error is caused by another error, that error can be retrieved with source().

Display representation

This error type follows anyhow’s display representation: when printed with display format ({}) (or converted to string) the error does not include a backtrace. Use the debug format ({:?}) to include the backtrace information.

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.

Custom(CustomError)

Implementations

impl Error

Error creation

pub fn custom(message: String) -> Self

pub fn custom_from<E: Error + Send + Sync + 'static>( message: String, cause: E, ) -> Self

impl Error

Access information about the error

pub fn message(&self) -> &str

pub fn backtrace(&self) -> &Backtrace

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)>

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 Error for Error

fn custom<T>(msg: T) -> Self

where T: Display,

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

impl Error for Error

fn custom<T>(msg: T) -> Self

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<CharTryFromError> for Error

fn from(err: CharTryFromError) -> Error

Converts to this type from the input type.

impl From<Error> for Error

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<Infallible> for Error

fn from(_: Infallible) -> Self

Converts to this type from the input type.

impl From<MarrowError> for Error

fn from(err: MarrowError) -> Self

Converts to this type from the input type.

impl From<ParseError> for Error

fn from(err: ParseError) -> Self

Converts to this type from the input type.

impl From<ParseIntError> for Error

fn from(err: ParseIntError) -> Self

Converts to this type from the input type.

impl From<PodCastError> for Error

fn from(err: PodCastError) -> Self

Converts to this type from the input type.

impl From<TryFromCharError> for Error

fn from(err: TryFromCharError) -> Error

impl From<Utf8Error> for Error

fn from(err: Utf8Error) -> Self

impl PartialEq for Error

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