Expand description

Decoding state machine

Variants§

§

ReadingFooter

Reading the last 8 bytes of the file

§

ReadingMetadata(FooterTail)

Reading the metadata thrift structure

§

ReadingPageIndex(Box<ParquetMetaData>)

§

Finished

§

Intermediate

State left during the try_decode method so something valid is present. This state should never be observed.
