Struct DeltaTablePartition 

pub struct DeltaTablePartition {
    pub key: String,
    pub value: Scalar,
}

The deltalake crate is currently just a meta-package shim for deltalake-core A Struct DeltaTablePartition used to represent a partition of a DeltaTable.

Fields

key: String

The key of the DeltaTable partition.

value: Scalar

The value of the DeltaTable partition.

Implementations

impl DeltaTablePartition

pub fn from_partition_value( partition_value: (&str, &Scalar), ) -> DeltaTablePartition

Create a DeltaTable partition from a Tuple of (key, value).

Trait Implementations

impl Clone for DeltaTablePartition

fn clone(&self) -> DeltaTablePartition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeltaTablePartition

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

Formats the value using the given formatter.

impl PartialEq for DeltaTablePartition

fn eq(&self, other: &DeltaTablePartition) -> 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 TryFrom<&str> for DeltaTablePartition

A HivePartition string is represented by a “key=value” format.

use deltalake_core::DeltaTablePartition;

let hive_part = "ds=2023-01-01";
let partition = DeltaTablePartition::try_from(hive_part).unwrap();
assert_eq!("ds", partition.key);
assert_eq!(Scalar::String("2023-01-01".into()), partition.value);

fn try_from(partition: &str) -> Result<DeltaTablePartition, DeltaTableError>

Try to create a DeltaTable partition from a HivePartition string. Returns a DeltaTableError if the string is not in the form of a HivePartition.

type Error = DeltaTableError

The type returned in the event of a conversion error.
