Trait Implementations

impl Debug for DecodingError

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

Formats the value using the given formatter.

impl Display for DecodingError

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

Formats the value using the given formatter.

impl Error for DecodingError

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

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

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

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl From<DecodingError> for Error

fn from(err: DecodingError) -> Error

Converts to this type from the input type.

impl From<Error> for DecodingError

fn from(err: Error) -> DecodingError

Converts to this type from the input type.

impl From<String> for DecodingError

fn from(err: String) -> DecodingError

Converts to this type from the input type.
