Enum Key 

pub enum Key {
    String(String),
    Integer(i64),
    Composite(Vec<Key>),
    Binary(Vec<u8>),
}

A database key - supports string, integer, and composite keys

Variants

String(String)

String key

Integer(i64)

Integer key

Composite(Vec<Key>)

Composite key (multiple parts)

Binary(Vec<u8>)

Binary key (hash)

Implementations

impl Key

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

Create a string key

pub fn integer(i: i64) -> Self

Create an integer key

pub fn composite(parts: Vec<Key>) -> Self

Create a composite key

pub fn binary(data: impl AsRef<[u8]>) -> Self

Create a binary key from bytes

pub fn hash(&self) -> [u8; 32]

Hash the key to a fixed-size binary representation

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

Convert key to bytes for hashing

pub fn to_qubit_index(&self, num_qubits: usize) -> usize

Map key to qubit index for quantum operations Uses hash to distribute keys uniformly across 2^n indices

Trait Implementations

impl Clone for Key

fn clone(&self) -> Key

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Key

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Key

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Key

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

Formats the value using the given formatter.

impl From<&str> for Key

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for Key

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<i64> for Key

fn from(i: i64) -> Self

Converts to this type from the input type.

impl Hash for Key

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 Key

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Key

impl StructuralPartialEq for Key
