Struct HCons 

pub struct HCons<H, T: HList>(pub H, pub T);

The “cons” of a head element of type H and a tail HList.

Tuple Fields

0: H

1: T

Implementations

impl<H, T: HList> HCons<H, T>

pub fn head(&self) -> &H

Returns a reference to the head element of this list.

pub fn tail(&self) -> &T

Returns a reference to the tail of this list.

Trait Implementations

impl<H: Clone, T: Clone + HList> Clone for HCons<H, T>

fn clone(&self) -> HCons<H, T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<H: Debug, T: Debug + HList> Debug for HCons<H, T>

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

Formats the value using the given formatter.

impl<H, T: HList> HList for HCons<H, T>

fn cons<X>(self, x: X) -> HCons<X, Self>

where Self: Sized,

Creates a new HCons with the given X value in head position.

impl<H: Hash, T: Hash + HList> Hash for HCons<H, T>

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<H: Ord, T: Ord + HList> Ord for HCons<H, T>

fn cmp(&self, other: &HCons<H, T>) -> 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<H: PartialEq, T: PartialEq + HList> PartialEq for HCons<H, T>

fn eq(&self, other: &HCons<H, T>) -> 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<H: PartialOrd, T: PartialOrd + HList> PartialOrd for HCons<H, T>

fn partial_cmp(&self, other: &HCons<H, T>) -> 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.
