Enum NeverAdapter

pub enum NeverAdapter {}

An immaterial type representing a data set adapter which is never required, and as such is never instantiated. Most transfer syntaxes use this, as they do not have to adapt readers and writers for encoding and decoding data sets. The main exception is in the family of Deflated Explicit VR Little Endian transfer syntaxes.

Trait Implementations

impl Clone for NeverAdapter

fn clone(&self) -> NeverAdapter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<R, W> DataRWAdapter<R, W> for NeverAdapter

type Reader = Box<dyn Read>

The type of the adapted reader.

type Writer = Box<dyn Write>

The type of the adapted writer.

fn adapt_reader(&self, _reader: R) -> Self::Reader

where R: Read,

Adapt a byte reader.

fn adapt_writer(&self, _writer: W) -> Self::Writer

where W: Write,

Adapt a byte writer.

impl Debug for NeverAdapter

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

Formats the value using the given formatter.

impl Hash for NeverAdapter

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for NeverAdapter

fn cmp(&self, other: &NeverAdapter) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for NeverAdapter

fn eq(&self, other: &NeverAdapter) -> 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.

impl PartialOrd for NeverAdapter

fn partial_cmp(&self, other: &NeverAdapter) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl PixelDataReader for NeverAdapter

fn decode( &self, _src: &dyn PixelDataObject, _dst: &mut Vec<u8>, ) -> DecodeResult<()>

Decode the given DICOM object containing encapsulated pixel data into native pixel data as a byte stream in little endian, appending these bytes to the given vector dst.

fn decode_frame( &self, _src: &dyn PixelDataObject, _frame: u32, _dst: &mut Vec<u8>, ) -> DecodeResult<()>

Decode the given DICOM object containing encapsulated pixel data into native pixel data of a single frame as a byte stream in little endian, appending these bytes to the given vector dst.

impl PixelDataWriter for NeverAdapter

fn encode( &self, _src: &dyn PixelDataObject, _options: EncodeOptions, _dst: &mut Vec<Vec<u8>>, _offset_table: &mut Vec<u32>, ) -> EncodeResult<Vec<AttributeOp>>

Encode a DICOM object’s image into the format supported by this adapter, writing a byte stream of pixel data fragment values to the given vector dst and the offsets to each decoded frame into offset_table.

fn encode_frame( &self, _src: &dyn PixelDataObject, _frame: u32, _options: EncodeOptions, _dst: &mut Vec<u8>, ) -> EncodeResult<Vec<AttributeOp>>

Encode a single frame of a DICOM object’s image into the format supported by this adapter, by writing a byte stream of pixel data values into the given destination. The bytes written comprise a single pixel data fragment in its entirety.
