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.

ReadMagicCode

Fields

backtrace: Backtrace

source: Error

The file meta group parser could not read the magic code DICM from its source.

ReadValueData

Fields

backtrace: Backtrace

source: Error

The file meta group parser could not fetch the value of a data element from its source.

AllocationSize

Fields

backtrace: Backtrace

source: TryReserveError

The parser could not allocate memory for the given length of a data element.

DecodeText

Fields

name: &'static str

source: DecodeTextError

The file meta group parser could not decode the text in one of its data elements.

NotDicom

Fields

backtrace: Backtrace

Invalid DICOM data, detected by checking the DICM code.

DecodeElement

Fields

source: Error

An issue occurred while decoding the next data element in the file meta data set.

UnexpectedTag

Fields

tag: Tag

backtrace: Backtrace

A data element with an unexpected tag was retrieved: the parser was expecting another tag first, or at least one that is part of the the file meta group.

MissingElement

Fields

alias: &'static str

backtrace: Backtrace

A required file meta data element is missing.

UnexpectedDataValueLength

Fields

tag: Tag

length: Length

backtrace: Backtrace

The value length of a data elements in the file meta group was unexpected.

UndefinedValueLength

Fields

tag: Tag

backtrace: Backtrace

The value length of a data element is undefined, but knowing the length is required in its context.

WriteSet

Fields

source: Error

The file meta group data set could not be written.

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, __snafu_display_formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Errorwhere
    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)>

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

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 ErrorCompat for Error

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.
