Implementations

impl InMemDicomObject<StandardDataDictionary>

pub fn create_empty() -> Self

👎Deprecated since 0.5.0: Use new_empty instead

Create a new empty DICOM object.

pub fn new_empty() -> Self

Create a new empty DICOM object.

pub fn from_element_source<I>(iter: I) -> Result<Self>where
    I: IntoIterator<Item = Result<InMemElement<StandardDataDictionary>>>,

Construct a DICOM object from a fallible source of structured elements.

pub fn from_element_iter<I>(iter: I) -> Selfwhere
    I: IntoIterator<Item = InMemElement<StandardDataDictionary>>,

Construct a DICOM object from a non-fallible source of structured elements.

pub fn read_dataset<S>(decoder: S) -> Result<Self>where
    S: StatefulDecode,

Read an object from a source using the given decoder.

Note: read_dataset_with_ts and read_dataset_with_ts_cs may be easier to use.

pub fn read_dataset_with_ts_cs<S>(
    from: S,
    ts: &TransferSyntax,
    cs: SpecificCharacterSet
) -> Result<Self>where
    S: Read,

Read an object from a source, using the given transfer syntax and default character set.

If the attribute Specific Character Set is found in the encoded data, this will override the given character set.

pub fn read_dataset_with_ts<S>(from: S, ts: &TransferSyntax) -> Result<Self>where
    S: Read,

Read an object from a source, using the given transfer syntax.

The default character set is assumed until Specific Character Set is found in the encoded data, after which the text decoder will be overriden accordingly.

impl<D> InMemDicomObject<D>where
    D: DataDictionary + Clone,

pub fn new_empty_with_dict(dict: D) -> Self

Create a new empty object, using the given dictionary for name lookup.

pub fn read_dataset_with_dict<S>(decoder: S, dict: D) -> Result<Self>where
    S: StatefulDecode,
    D: DataDictionary,

pub fn read_dataset_with_dict_ts<S>(
    from: S,
    dict: D,
    ts: &TransferSyntax
) -> Result<Self>where
    S: Read,
    D: DataDictionary,

Read an object from a source, using the given data dictionary and transfer syntax.

pub fn read_dataset_with_dict_ts_cs<S>(
    from: S,
    dict: D,

    cs: SpecificCharacterSet
) -> Result<Self>where
    S: Read,
    D: DataDictionary,

Read an object from a source, using the given data dictionary, transfer syntax, and the given character set to assume by default.

If the attribute Specific Character Set is found in the encoded data, this will override the given character set.

pub fn meta(&self) -> Option<&FileMetaTable>

👎Deprecated since 0.5.3: Always returns None, see FileDicomObject::meta instead

Retrieve the object’s meta table if available.

At the moment, this is sure to return None, because the meta table is kept in a separate wrapper value.

pub fn element(&self, tag: Tag) -> Result<&InMemElement<D>>

Retrieve a particular DICOM element by its tag.

An error is returned if the element does not exist. For an alternative to this behavior, see element_opt.

pub fn element_by_name(&self, name: &str) -> Result<&InMemElement<D>>

Retrieve a particular DICOM element by its name.

This method translates the given attribute name into its tag before retrieving the element. If the attribute is known in advance, using element with a tag constant is preferred.

An error is returned if the element does not exist. For an alternative to this behavior, see element_by_name_opt.

pub fn element_opt(&self, tag: Tag) -> Result<Option<&InMemElement<D>>>

Retrieve a particular DICOM element that might not exist by its tag.

If the element does not exist, None is returned.

pub fn element_by_name_opt(&self, name: &str) -> Result<Option<&InMemElement<D>>>

Retrieve a particular DICOM element that might not exist by its name.

If the element does not exist, None is returned.

This method translates the given attribute name into its tag before retrieving the element. If the attribute is known in advance, using element_opt with a tag constant is preferred.

pub fn put(&mut self, elt: InMemElement<D>) -> Option<InMemElement<D>>

Insert a data element to the object, replacing (and returning) any previous element of the same attribute.

pub fn put_element(&mut self, elt: InMemElement<D>) -> Option<InMemElement<D>>

Insert a data element to the object, replacing (and returning) any previous element of the same attribute.

pub fn remove_element(&mut self, tag: Tag) -> bool

Remove a DICOM element by its tag, reporting whether it was present.

pub fn remove_element_by_name(&mut self, name: &str) -> Result<bool>

Remove a DICOM element by its keyword, reporting whether it was present.

pub fn take_element(&mut self, tag: Tag) -> Result<InMemElement<D>>

Remove and return a particular DICOM element by its tag.

pub fn take_element_by_name(&mut self, name: &str) -> Result<InMemElement<D>>

Remove and return a particular DICOM element by its name.

pub fn retain(&mut self, f: impl FnMut(&InMemElement<D>) -> bool)

Modify the object by retaining only the DICOM data elements specified by the predicate.

The elements are visited in ascending tag order, and those for which f(&element) returns false are removed.

pub fn write_dataset<W, E>(&self, to: W, encoder: E) -> Result<()>where
    W: Write,
    E: EncodeTo<W>,

Write this object’s data set into the given writer, with the given encoder specifications, without preamble, magic code, nor file meta group.

The text encoding to use will be the default character set until Specific Character Set is found in the data set, in which then that character set will be used.

Note: write_dataset_with_ts and write_dataset_with_ts_cs may be easier to use.

pub fn write_dataset_with_ts_cs<W>(
    &self,
    to: W,
    ts: &TransferSyntax,
    cs: SpecificCharacterSet
) -> Result<()>where
    W: Write,

Write this object’s data set into the given printer, with the specified transfer syntax and character set, without preamble, magic code, nor file meta group.

If the attribute Specific Character Set is found in the data set, the last parameter is overridden accordingly.

pub fn write_dataset_with_ts<W>(&self, to: W, ts: &TransferSyntax) -> Result<()>where
    W: Write,

Write this object’s data set into the given writer, with the specified transfer syntax, without preamble, magic code, nor file meta group.

The default character set is assumed until the Specific Character Set is found in the data set, after which the text encoder is overridden accordingly.

pub fn with_exact_meta(self, meta: FileMetaTable) -> FileDicomObject<Self>

Encapsulate this object to contain a file meta group as described exactly by the given table.

Note: this method will not adjust the file meta group to be semantically valid for the object.

pub fn with_meta(
    self,
    meta: FileMetaTableBuilder
) -> Result<FileDicomObject<Self>>

Encapsulate this object to contain a file meta group, created through the given file meta table builder.

The attribute Media Storage SOP Instance UID will be filled in with the contents of the object, if the attribute SOP Instance UID is present. A complete file meta group should still provide the media storage SOP class UID and transfer syntax.

pub fn iter(&self) -> impl Iterator<Item = &InMemElement<D>> + '_

Obtain an iterator over the elements of this object.

pub fn tags(&self) -> impl Iterator<Item = Tag> + '_

Obtain an iteartor over the tags of the object’s elements.
