Enum Partitioning 

pub enum Partitioning {
    Auto,
    Hive,
    None,
}

How hive-style partition columns (key=value/ path segments) are handled for an S3 parquet source. Local parquet always auto-detects; this option brings S3 in line and lets you force or disable the behaviour.

Variants

Auto

Detect key=value segments from the location glob or by listing the prefix. No partition columns are added when none are found.

Hive

Force hive partitioning. Partition keys are taken from the location glob, or discovered by listing the prefix.

None

Treat the source as a flat set of parquet files — never add partition columns even if the path looks hive-partitioned.

Implementations

impl Partitioning

pub fn as_str(self) -> &'static str

Trait Implementations

impl Clone for Partitioning

fn clone(&self) -> Partitioning

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Partitioning

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

Formats the value using the given formatter.

impl Default for Partitioning

fn default() -> Partitioning

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Partitioning

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Partitioning

fn eq(&self, other: &Partitioning) -> 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.
