Struct KeyValuePair

pub struct KeyValuePair<K, V> { /* private fields */ }

A general data structure holding a key and value pair.

Implementations

impl<K: Copy, V> KeyValuePair<K, V>

pub fn key(&self) -> K

Get the key.

Examples

let kv = KeyValuePair::new("TheKey", 42.0);
assert_eq!("TheKey", kv.key());

impl<K, V: Copy> KeyValuePair<K, V>

pub fn value(&self) -> V

Get the value.

Examples

let kv = KeyValuePair::new("TheKey", 42.0);
assert_eq!(42.0, kv.value());

impl<K, V> KeyValuePair<K, V>

pub fn key_ref(&self) -> &K

Get the key.

Examples

let kv = KeyValuePair::new("TheKey", 42.0);
assert_eq!("TheKey", *kv.key_ref());

pub fn value_ref(&self) -> &V

Get the value.

Examples

let kv = KeyValuePair::new("TheKey", 42.0);
assert_eq!(42.0, *kv.value_ref());

pub fn new(key: K, value: V) -> Self

Create a KewValuePair.

Examples

let kv = KeyValuePair::new("TheKey", 42.0);
assert_eq!("TheKey", kv.key());
assert_eq!(42.0, kv.value());

Trait Implementations

impl<K: Clone, V: Clone> Clone for KeyValuePair<K, V>

fn clone(&self) -> KeyValuePair<K, V>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<K: Debug, V: Debug> Debug for KeyValuePair<K, V>

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

Formats the value using the given formatter.

impl<'de, K, V> Deserialize<'de> for KeyValuePair<K, V>

where K: Deserialize<'de>, V: Deserialize<'de>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<K: Hash, V: Hash> Hash for KeyValuePair<K, V>

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<K: PartialEq, V: PartialEq> PartialEq for KeyValuePair<K, V>

fn eq(&self, other: &KeyValuePair<K, V>) -> 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<K, V> Serialize for KeyValuePair<K, V>

where K: Serialize, V: Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
