Enum ParquetError

#[non_exhaustive]

Errors generated by this crate

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.

OutOfSpec(String)

When the parquet file is known to be out of spec.

FeatureNotActive(Feature, String)

Error presented when trying to use a code branch that requires activating a feature.

FeatureNotSupported(String)

Error presented when trying to use a feature from parquet that is not yet supported

InvalidParameter(String)

When encoding, the user passed an invalid parameter

WouldOverAllocate

When decoding or decompressing, the page would allocate more memory than allowed

Trait Implementations

impl Clone for ParquetError

fn clone(&self) -> ParquetError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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
