Parquet error enumeration

Variants§

§

General(String)

General Parquet error. Returned when code violates normal workflow of working with Parquet files.

§

NYI(String)

“Not yet implemented” Parquet error. Returned when functionality is not yet available.

§

EOF(String)

“End of file” Parquet error. Returned when IO related failures occur, e.g. when there are not enough bytes to decode.

§

ArrowError(String)

Arrow error. Returned when reading into arrow or writing from arrow.

§

IndexOutOfBound(usize, usize)

§

External(Box<dyn Error + Send + Sync>)

An external error variant
