Enum dicom_object::AtAccessError

#[non_exhaustive]
pub enum AtAccessError {
    MissingSequence {
        selector: AttributeSelector,
        step_index: u32,
    },
    NotASequence {
        selector: AttributeSelector,
        step_index: u32,
    },
    MissingLeafElement {
        selector: AttributeSelector,
    },
}

An error which may occur when looking up a DICOM object’s attributes at an arbitrary depth, such as through value_at.

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.

MissingSequence

Fields

selector: AttributeSelector

step_index: u32

Missing itermediate sequence for {selector} at step {step_index}

NotASequence

Fields

selector: AttributeSelector

step_index: u32

Step {step_index} for {selector} is not a data set sequence

MissingLeafElement

Fields

selector: AttributeSelector

Missing element at last step for {selector}

Trait Implementations

impl Debug for AtAccessError

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

Formats the value using the given formatter.

impl Display for AtAccessError

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

Formats the value using the given formatter.

impl Error for AtAccessErrorwhere 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, 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 AtAccessError

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.
