Struct Pair 

pub struct Pair<First, Second>(pub First, pub Second);

Wraps two values.

A simple tuple struct that holds two values of potentially different types.

Higher-Kinded Type Representation

This type has multiple higher-kinded representations:

• PairBrand: fully polymorphic over both values (bifunctor).
• PairWithFirstBrand<First>: the first value type is fixed, polymorphic over the second (functor over second).
• PairWithSecondBrand<Second>: the second value type is fixed, polymorphic over the first (functor over first).

Serialization

This type supports serialization and deserialization via serde when the serde feature is enabled.

• First: The type of the first value.
• Second: The type of the second value.

Fields

• 0: The first value.
• 1: The second value.

Examples

use fp_library::types::*;

let p = Pair(1, "hello");
assert_eq!(p.0, 1);
assert_eq!(p.1, "hello");

Tuple Fields

0: First

1: Second

Trait Implementations

impl<First: Clone, Second: Clone> Clone for Pair<First, Second>

fn clone(&self) -> Pair<First, Second>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<First: Debug, Second: Debug> Debug for Pair<First, Second>

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

Formats the value using the given formatter.

impl<First: Default, Second: Default> Default for Pair<First, Second>

fn default() -> Pair<First, Second>

Returns the “default value” for a type.

impl<'de, First, Second> Deserialize<'de> for Pair<First, Second>

where First: Deserialize<'de>, Second: Deserialize<'de>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<First: Hash, Second: Hash> Hash for Pair<First, Second>

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<First: Ord, Second: Ord> Ord for Pair<First, Second>

fn cmp(&self, other: &Pair<First, Second>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<First: PartialEq, Second: PartialEq> PartialEq for Pair<First, Second>

fn eq(&self, other: &Pair<First, Second>) -> 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<First: PartialOrd, Second: PartialOrd> PartialOrd for Pair<First, Second>

fn partial_cmp(&self, other: &Pair<First, Second>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<First, Second> Serialize for Pair<First, Second>

where First: Serialize, Second: Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<First: Copy, Second: Copy> Copy for Pair<First, Second>
