Trait dicom_encoding::decode::Decode

pub trait Decode {
    type Source: ?Sized + Read;
    fn decode_header(
        &self, 
        source: &mut Self::Source
    ) -> Result<DataElementHeader>;
    fn decode_item_header(

}

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.

Associated Types

type Source: ?Sized + Read

The data source's type.

Required methods

fn decode_header(&self, source: &mut Self::Source) -> Result<DataElementHeader>

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.

fn decode_item_header(
    &self,
    source: &mut Self::Source
) -> 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 Self::Source) -> Result<Tag>

Decode a DICOM attribute tag from the given source.
