Struct Triple 

pub struct Triple<A, B, C> {
    pub fst: A,
    pub snd: B,
    pub thd: C,
}

A generic ordered triple.

Fields

fst: A

First component.

snd: B

Second component.

thd: C

Third component.

Implementations

impl<A, B, C> Triple<A, B, C>

pub fn new(fst: A, snd: B, thd: C) -> Self

Construct a triple.

pub fn from_tuple((a, b, c): (A, B, C)) -> Self

Construct from a Rust 3-tuple.

pub fn into_tuple(self) -> (A, B, C)

Convert to a Rust 3-tuple.

pub fn trimap<D, E, F>( self, f: impl FnOnce(A) -> D, g: impl FnOnce(B) -> E, h: impl FnOnce(C) -> F, ) -> Triple<D, E, F>

Map all three components.

pub fn fst_pair(self) -> Pair<A, B>

Project the first pair.

pub fn snd_pair(self) -> Pair<B, C>

Project the last pair.

Trait Implementations

impl<A: Clone, B: Clone, C: Clone> Clone for Triple<A, B, C>

fn clone(&self) -> Triple<A, B, C>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<A: Debug, B: Debug, C: Debug> Debug for Triple<A, B, C>

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

Formats the value using the given formatter.

impl<A: Default, B: Default, C: Default> Default for Triple<A, B, C>

fn default() -> Triple<A, B, C>

Returns the “default value” for a type.

impl<A: Hash, B: Hash, C: Hash> Hash for Triple<A, B, C>

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<A: PartialEq, B: PartialEq, C: PartialEq> PartialEq for Triple<A, B, C>

fn eq(&self, other: &Triple<A, B, C>) -> 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.
