Trait dicom_encoding::decode::DecodeFrom

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

Type trait for reading and decoding DICOM data elements from a specific source

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

Required methods

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

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(&self, source: &mut S) -> Result<SequenceItemHeader>

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(&self, source: &mut S) -> Result<Tag>

Decode a DICOM attribute tag from the given source.
