[−][src]Trait dicom_encoding::decode::Decode

pub trait Decode {
    fn decode_header<S: ?Sized>(
        &self, 
        source: &mut S
    ) -> Result<(DataElementHeader, usize)>
    where
        S: Read;

    fn decode_item_header<S: ?Sized>(
        &self, 
        source: &mut S
    ) -> Result<SequenceItemHeader>
    where
        S: Read;

    fn decode_tag<S: ?Sized>(&self, source: &mut S) -> Result<Tag>
    where
        S: Read;
}

Type trait for reading and decoding DICOM data elements.

  • The specific behaviour of decoding, even when abstracted from the original source,
  • may depend on the transfer syntax.

Required methods

fn decode_header<S: ?Sized>(
    &self,
    source: &mut S
) -> Result<(DataElementHeader, usize)> where
    S: Read, 

Fetch and decode the next data element header from the given source.

  • This method returns only the header of the element. At the end of this operation, the source
  • will be pointing at the element's value data, which should be read or skipped as necessary.
  • Decoding an item or sequence delimiter is considered valid, and so should be properly handled
  • by the decoder. The value representation in this case should be UN.
  • Returns the expected header and the exact number of bytes read from the source.

fn decode_item_header<S: ?Sized>(
    &self,
    source: &mut S
) -> Result<SequenceItemHeader> where
    S: Read, 

Fetch and decode the next sequence item head from the given source. It is a separate method

  • because value representation is always implicit when reading item headers and delimiters.
  • This method returns only the header of the item. At the end of this operation, the source
  • will be pointing at the beginning of the item's data, which should be traversed if necessary.

fn decode_tag<S: ?Sized>(&self, source: &mut S) -> Result<Tag> where
    S: Read, 

Decode a DICOM attribute tag from the given source.
