Struct PartitionField

pub struct PartitionField {
    pub source_id: i32,
    pub field_id: i32,
    pub name: String,
    pub transform: Transform,
}

Partition fields capture the transform from table data to partition values.

Fields

source_id: i32

A source column id from the table’s schema

field_id: i32

A partition field id that is used to identify a partition field and is unique within a partition spec. In v2 table metadata, it is unique across all partition specs.

name: String

A partition name.

transform: Transform

A transform that is applied to the source column to produce a partition value.

Implementations

impl PartitionField

pub fn builder() -> PartitionFieldBuilder<((), (), (), ())>

Create a builder for building PartitionField. On the builder, call .source_id(...), .field_id(...), .name(...), .transform(...) to set the values of the fields. Finally, call .build() to create the instance of PartitionField.

impl PartitionField

pub fn into_unbound(self) -> UnboundPartitionField

To unbound partition field

Trait Implementations

impl Clone for PartitionField

fn clone(&self) -> PartitionField

Returns a copy 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

Formats the value using the given formatter.

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

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<PartitionField> for UnboundPartitionField

fn from(field: PartitionField) -> Self

Converts to this type from the input type.

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::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
