Parquet error enumeration

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future 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)

Error when the requested column index is more than the number of columns in the row group

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

An external error variant

NeedMoreData(usize)

Returned when a function needs more data to complete properly. The usize field indicates the total number of bytes required, not the number of additional bytes.

NeedMoreDataRange(Range<u64>)

Returned when a function needs more data to complete properly. The Range<u64> indicates the range of bytes that are needed.

Trait Implementations

impl Debug for ParquetError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ParquetError

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ParquetError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
