Enum PartitionKey 

pub enum PartitionKey {
    String(String),
    Int(i64),
    Composite(Vec<PartitionKey>),
    Uuid(String),
    Bytes(Vec<u8>),
}

A partition key for routing data to shards.

Variants

String(String)

String key.

Int(i64)

Integer key.

Composite(Vec<PartitionKey>)

Composite key (multiple values).

Uuid(String)

UUID key.

Bytes(Vec<u8>)

Bytes key.

Implementations

impl PartitionKey

pub fn string(value: impl Into<String>) -> Self

Create a string partition key.

pub fn int(value: i64) -> Self

Create an integer partition key.

pub fn composite(keys: Vec<PartitionKey>) -> Self

Create a composite partition key.

pub fn uuid(value: impl Into<String>) -> Self

Create a UUID partition key.

pub fn hash_value(&self) -> u64

Compute the hash for this partition key.

pub fn to_bytes(&self) -> Vec<u8>

Convert to bytes representation.

Trait Implementations

impl Clone for PartitionKey

fn clone(&self) -> PartitionKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PartitionKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PartitionKey

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&str> for PartitionKey

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<String> for PartitionKey

fn from(value: String) -> Self

Converts to this type from the input type.

impl From<i32> for PartitionKey

fn from(value: i32) -> Self

Converts to this type from the input type.

impl From<i64> for PartitionKey

fn from(value: i64) -> Self

Converts to this type from the input type.

impl Hash for PartitionKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PartitionKey

fn eq(&self, other: &PartitionKey) -> 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 PartitionKey

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
