Struct DecodeError 

pub struct DecodeError<E: DeErr + Send + Sync> { /* private fields */ }

Error type for deserialization failures.

This struct wraps format-agnostic decoding errors from various serialization backends (JSON, msgpack, etc.). It uses thiserror to provide consistent error formatting and conversion from format-specific error types.

The underlying error is boxed to allow different serialization formats to contribute their own error types without requiring a large enum variant.

Trait Implementations

impl<E: Debug + DeErr + Send + Sync> Debug for DecodeError<E>

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

Formats the value using the given formatter.

impl<E> Display for DecodeError<E>

where E: Display + DeErr + Send + Sync,

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

Formats the value using the given formatter.

impl<E: DeErr + Send + Sync> Error for DecodeError<E>

where Self: Debug + Display,

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<DecodeErrorType: DeErr + Send + Sync> From<DecodeError<DecodeErrorType>> for SubError<DecodeErrorType>

fn from(source: DecodeError<DecodeErrorType>) -> Self

Converts to this type from the input type.
