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

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

Fields

backtrace: Backtrace

source: Error

ReadValueData

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

Fields

backtrace: Backtrace

source: Error

AllocationSize

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

Fields

backtrace: Backtrace

source: TryReserveError

DecodeText

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

Fields

name: Cow<'static, str>

source: DecodeTextError

NotDicom

Invalid DICOM data, detected by checking the DICM code.

Fields

backtrace: Backtrace

DecodeElement

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

Fields

source: Error

UnexpectedTag

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.

Fields

tag: Tag

backtrace: Backtrace

MissingElement

A required file meta data element is missing.

Fields

alias: &'static str

backtrace: Backtrace

UnexpectedDataValueLength

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

Fields

tag: Tag

length: Length

backtrace: Backtrace

UndefinedValueLength

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

Fields

tag: Tag

backtrace: Backtrace

WriteSet

The file meta group data set could not be written.

Fields

source: Error

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 Error

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 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.
