Trait TaggedDecode 

pub trait TaggedDecode: Decode {
    type Tag;

    // Required method
    fn start_decoding(&mut self, tag: Self::Tag) -> Result<()>;
}

This trait allows for decoding tagged items from a byte sequence incrementally.

Required Associated Types

type Tag

The type of tags prefixed to the items to be decoded.

Required Methods

fn start_decoding(&mut self, tag: Self::Tag) -> Result<()>

Prepares to start decoding an item tagged by tag.

Errors

The following errors may be returned by the decoder:

• ErrorKind::InvalidInput:
  • Unexpected tag was passed
• ErrorKind::IncompleteDecoding:
  • The previous decoding process has not been completed
• ErrorKind::DecoderTerminated:
  • The decoder has terminated (i.e., cannot decode any more items)
• ErrorKind::Other:
  • Other errors has occurred
