Struct phantom_type::PhantomType

pub struct PhantomType<T: ?Sized>(_);

A PhantomData analog which prevents "parameter is never used" error, but does not produce any restrictions in contrast with PhantomData.

Trait Implementations

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

fn clone(&self) -> Self

Returns a copy of the value.

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

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

Formats the value using the given formatter.

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

fn default() -> Self

Returns the "default value" for a type.

impl<T: ?Sized> Eq for PhantomType<T>

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

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

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

This method returns an Ordering between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

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

fn eq(&self, other: &Self) -> bool

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

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

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

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

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

#[must_use]fn lt(&self, other: &Rhs) -> bool

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

#[must_use]fn le(&self, other: &Rhs) -> bool

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

#[must_use]fn gt(&self, other: &Rhs) -> bool

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

#[must_use]fn ge(&self, other: &Rhs) -> bool

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