Struct gazebo::phantom::PhantomDataInvariant

pub struct PhantomDataInvariant<T: ?Sized>(_);

A type like PhantomData, but where the contained T is invariant in both lifetimes and types. See variance on the Nomicon for an explanation of these terms.

pub const fn new() -> Self

Trait Implementations

impl<T: ?Sized> Clone for PhantomDataInvariant<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: ?Sized> Debug for PhantomDataInvariant<T>

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

Formats the value using the given formatter.

impl<T: ?Sized> Default for PhantomDataInvariant<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: ?Sized> Dupe for PhantomDataInvariant<T>

fn dupe(&self) -> Self

impl<T: ?Sized> Hash for PhantomDataInvariant<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,

Feeds a slice of this type into the given Hasher.

impl<T: ?Sized> Ord for PhantomDataInvariant<T>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

const fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl<T: ?Sized> PartialEq<PhantomDataInvariant<T>> for PhantomDataInvariant<T>

fn eq(&self, other: &PhantomDataInvariant<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: ?Sized> PartialOrd<PhantomDataInvariant<T>> for PhantomDataInvariant<T>

fn partial_cmp(&self, other: &PhantomDataInvariant<T>) -> Option<Ordering>

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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