pub fn from_reader<R: Read>(reader: R) -> FromReaderIter<R> ⓘExpand description
Parse a reader into a lazy iterator of OwnedSegments.
Returns a FromReaderIter that parses and yields segments on demand,
keeping memory bounded. Use from_reader_collect to eagerly materialise
all segments into a Vec.
§Errors
Each next() call yields Some(Ok(segment)) for a successfully parsed
segment, Some(Err(EdifactError)) for a parse or I/O failure, and None
when the end of the stream has been reached.
