Possible errors that can arise during decoding.

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.

IoError(Error)

A std::io::Error encountered while deserializing.

FromUtf8Error(FromUtf8Error)

A std::string::FromUtf8Error encountered while decoding a UTF-8 String from the input data.

UnrecognizedDocumentElementType

While decoding a Document from bytes, an unexpected or unsupported element type was encountered.

Fields of UnrecognizedDocumentElementType

key: String

The key at which an unexpected/unsupported element type was encountered.

element_type: u8

The encountered element type.

SyntaxError

There was an error with the syntactical structure of the BSON.

Fields of SyntaxError

message: String

EndOfStream

The end of the BSON input was reached too soon.

InvalidTimestamp(i64)

An invalid timestamp was encountered while decoding.

AmbiguousTimestamp(i64)

An ambiguous timestamp was encountered while decoding.

DeserializationError

A general error encountered during deserialization. See: https://docs.serde.rs/serde/de/trait.Error.html

Fields of DeserializationError

message: String

A message describing the error.

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, fmt: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Error for Error

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

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()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

impl Error for Error

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

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<Error> for Error

fn from(err: Error) -> Error

Performs the conversion.

impl From<FromUtf8Error> for Error

fn from(err: FromUtf8Error) -> Error

Performs the conversion.
