DICOM File Meta Information Table.

This data type contains the relevant parts of the file meta information table, as specified in part 6, chapter 7 of the standard.

Creating a new file meta table from scratch is more easily done using a FileMetaTableBuilder. When modifying the struct’s public fields, it is possible to update the information group length through method update_information_group_length.

source_application_entity_title: Option<String>

Source Application Entity Title

sending_application_entity_title: Option<String>

Implementations

impl FileMetaTable

pub fn from_reader<R: Read>(file: R) -> Result<Self, Error>

Construct a file meta group table by parsing a DICOM data set from a reader.

pub fn transfer_syntax(&self) -> &str

Getter for the transfer syntax UID, with trailing characters already excluded.

pub fn media_storage_sop_instance_uid(&self) -> &str

Getter for the media storage SOP instance UID, with trailing characters already excluded.

pub fn media_storage_sop_class_uid(&self) -> &str

Getter for the media storage SOP class UID, with trailing characters already excluded.

pub fn implementation_class_uid(&self) -> &str

Getter for the implementation class UID, with trailing characters already excluded.

pub fn private_information_creator_uid(&self) -> Option<&str>

Getter for the private information creator UID, with trailing characters already excluded.

pub fn set_transfer_syntax<D, R, W>(&mut self, ts: &TransferSyntax<D, R, W>)

Set the file meta table’s transfer syntax according to the given transfer syntax descriptor.

This replaces the table’s transfer syntax UID to the given transfer syntax, without padding to even length. The information group length field is automatically recalculated.

pub fn update_information_group_length(&mut self)

Calculate the expected file meta group length according to the file meta attributes currently set, and assign it to the field information_group_length.

pub fn into_element_iter( self, ) -> impl Iterator<Item = DataElement<EmptyObject, [u8; 0]>>

Create an iterator over the defined data elements of the file meta group, consuming the file meta table.

See to_element_iter for a version which copies the element from the table.

pub fn to_element_iter( &self, ) -> impl Iterator<Item = DataElement<EmptyObject, [u8; 0]>> + '_

Create an iterator of data elements copied from the file meta group.

See into_element_iter for a version which consumes the table.

pub fn write<W: Write>(&self, writer: W) -> Result<(), Error>

Trait Implementations

impl ApplyOp for FileMetaTable

fn apply(&mut self, op: AttributeOp) -> ApplyResult

Apply the given attribute operation on this file meta information table.

See the dicom_core::ops module for more information.

type Err = ApplyError

The operation error type

impl Clone for FileMetaTable

fn clone(&self) -> FileMetaTable

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FileMetaTable

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

Formats the value using the given formatter.

impl PartialEq for FileMetaTable

fn eq(&self, other: &FileMetaTable) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
