pub struct DeserializeError { /* fields omitted */ }

An Serde deserialization error.

Methods

impl DeserializeError

pub fn field(&self) -> Option<u64>

Return the field index (starting at 0) of this error, if available.

pub fn kind(&self) -> &DeserializeErrorKind

Return the underlying error kind.

Trait Implementations

impl Clone for DeserializeError

fn clone(&self) -> DeserializeError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DeserializeError

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

Formats the value using the given formatter.

impl Display for DeserializeError

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

Formats the value using the given formatter.

impl Eq for DeserializeError

impl Error for DeserializeError

fn description(&self) -> &str

Deprecated since 1.41.0:

use the Display impl or to_string()

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

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

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl Error for DeserializeError

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

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 PartialEq<DeserializeError> for DeserializeError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
