Struct CompositeKey 

pub struct CompositeKey { /* private fields */ }

A composite partitioning key.

Implementations

impl CompositeKey

pub fn new() -> Self

Creates an empty composite key.

pub fn from_parts(parts: Vec<PartitionKey>) -> Self

Creates a composite key from parts.

pub fn with_part(self, part: PartitionKey) -> Self

Adds a partition key part.

pub fn parts(&self) -> &[PartitionKey]

Returns all parts.

Trait Implementations

impl Clone for CompositeKey

fn clone(&self) -> CompositeKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompositeKey

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

Formats the value using the given formatter.

impl Default for CompositeKey

fn default() -> CompositeKey

Returns the “default value” for a type.

impl PartialEq for CompositeKey

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