Sourcepub fn get(
&mut self,
offset: u32,
) -> Result<Option<&KvReader<FieldId>>, DocumentsBatchCursorError>
pub fn get( &mut self, offset: u32, ) -> Result<Option<&KvReader<FieldId>>, DocumentsBatchCursorError>
Returns a single document from the database.
Sourcepub fn next_document(
&mut self,
) -> Result<Option<&KvReader<FieldId>>, DocumentsBatchCursorError>
pub fn next_document( &mut self, ) -> Result<Option<&KvReader<FieldId>>, DocumentsBatchCursorError>
Returns the next document, starting from the first one. Subsequent calls to
next_document advance the document reader until all the documents have been read.
