Enum AttributeError 

#[non_exhaustive]
pub enum AttributeError {
    Custom {
        message: String,
        source: Option<Box<dyn Error + Send + Sync + 'static>>,
    },
    ConvertValue {
        source: ConvertValueError,
    },
    NotDataSet,
    DataSetItemOutOfBounds,
    NotPixelData,
    FragmentOutOfBounds,
}

An error which occurs when fetching a value

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

A custom error when encoding fails. Read the message and the underlying source for more details.

Fields

message: String

The error message.

source: Option<Box<dyn Error + Send + Sync + 'static>>

The underlying error cause, if any.

ConvertValue

the value cannot be converted to the requested type

Fields

source: ConvertValueError

NotDataSet

the value is not a data set sequence

DataSetItemOutOfBounds

the requested item index does not exist

NotPixelData

the value is not a pixel data element

FragmentOutOfBounds

the requested pixel data fragment index does not exist

Trait Implementations

impl Debug for AttributeError

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

Formats the value using the given formatter.

impl Display for AttributeError

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

Formats the value using the given formatter.

impl Error for AttributeError

where Self: Debug + Display,

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

Returns the lower-level source of this error, if any.

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 ErrorCompat for AttributeError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.

impl FromString for AttributeError

type Source = Box<dyn Error + Sync + Send>

The underlying error

fn without_source(message: String) -> Self

Create a brand new error from the given string

fn with_source(error: Self::Source, message: String) -> Self

Wrap an existing error with the given string
