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

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<(), Error>

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) -> DFParquetWriterVersion

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<DFParquetWriterVersion, <DFParquetWriterVersion as FromStr>::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.
