PartitionField : Partition field definition

Fields

field_id: String

Unique identifier for this partition field (must not be renamed)

source_ids: Vec<i32>

Field IDs of the source columns in the schema

transform: Option<Box<PartitionTransform>>

Well-known partition transform. Exactly one of transform or expression must be specified.

expression: Option<String>

DataFusion SQL expression using col0, col1, … as column references. Exactly one of transform or expression must be specified.

result_type: Box<JsonArrowDataType>

The output type of the partition value (JsonArrowDataType format)

Implementations

impl PartitionField

pub fn new( field_id: String, source_ids: Vec<i32>, result_type: JsonArrowDataType, ) -> PartitionField

Partition field definition

Trait Implementations

impl Clone for PartitionField

fn clone(&self) -> PartitionField

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PartitionField

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

Formats the value using the given formatter.

impl Default for PartitionField

fn default() -> PartitionField

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PartitionField

fn deserialize<__D>( __deserializer: __D, ) -> Result<PartitionField, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PartitionField

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

impl Serialize for PartitionField

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
