Enum ValueReadStrategy

pub enum ValueReadStrategy {
    Interpreted,
    Preserved,
    Raw,
}

The value reading strategy for the data set reader.

It defines how the PrimitiveValues in value tokens are constructed.

Variants

Interpreted

Textual values will be decoded according to their value representation.

Word-sized binary values are read according to the expected byte order. Dates, times, and date-times (DA, DT, TM) are parsed into their more specific variants, leading to parser failure if they are not valid DICOM. String numbers (IS, FD) are also converted into binary representations. For the case of floats, this may introduce precision errors.

Preserved

Values will be stored without decoding dates or textual numbers.

Word-sized binary values are read according to the expected byte order. Date-time values and numbers are kept in their original string representation as string objects. All text is still decoded into Rust string values, in accordance to the standard, unless its value representation is unknown to the decoder.

This is the default strategy.

Raw

All primitive values are fetched as raw byte buffers, without any form of decoding or interpretation. Not even byte order conversions are made.

This strategy is not recommended, as it makes the retrieval of important textual data more difficult.

Trait Implementations

impl Clone for ValueReadStrategy

fn clone(&self) -> ValueReadStrategy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ValueReadStrategy

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

Formats the value using the given formatter.

impl Default for ValueReadStrategy

fn default() -> ValueReadStrategy

Returns the “default value” for a type.

impl Hash for ValueReadStrategy

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 PartialEq for ValueReadStrategy

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