Enum DFParquetWriterVersion 

pub enum DFParquetWriterVersion {
    V1_0,
    V2_0,
}

Parquet writer version options for controlling the Parquet file format version

This enum validates parquet writer version values at configuration time, ensuring only valid versions (“1.0” or “2.0”) can be set via SET commands or proto deserialization.

Variants

V1_0

Parquet format version 1.0

V2_0

Parquet format version 2.0

Trait Implementations

impl Clone for DFParquetWriterVersion

fn clone(&self) -> DFParquetWriterVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ConfigField for DFParquetWriterVersion

fn visit<V: Visit>(&self, v: &mut V, key: &str, description: &'static str)

fn set(&mut self, _: &str, value: &str) -> Result<()>

fn reset(&mut self, key: &str) -> Result<()>

impl Debug for DFParquetWriterVersion

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

Formats the value using the given formatter.

impl Default for DFParquetWriterVersion

fn default() -> DFParquetWriterVersion

Returns the “default value” for a type.

impl Display for DFParquetWriterVersion

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

Formats the value using the given formatter.

impl From<DFParquetWriterVersion> for WriterVersion

Available on crate feature parquet only.

Convert DFParquetWriterVersion to parquet crate’s WriterVersion

This conversion is infallible since DFParquetWriterVersion only contains valid values that have been validated at configuration time.

fn from(value: DFParquetWriterVersion) -> Self

Converts to this type from the input type.

impl From<WriterVersion> for DFParquetWriterVersion

Available on crate feature parquet only.

Convert parquet crate’s WriterVersion to DFParquetWriterVersion

This is used when converting from existing parquet writer properties, such as when reading from proto or test code.

fn from(version: WriterVersion) -> Self

Converts to this type from the input type.

impl FromStr for DFParquetWriterVersion

Implement parsing strings to DFParquetWriterVersion

type Err = DataFusionError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for DFParquetWriterVersion

fn eq(&self, other: &DFParquetWriterVersion) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
