Trait Implementations

impl<Meta: Clone + VmMeta> Clone for MaybeInvalidPPN<Meta>

fn clone(&self) -> MaybeInvalidPPN<Meta>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Meta: Hash + VmMeta> Hash for MaybeInvalidPPN<Meta>

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<Meta: Ord + VmMeta> Ord for MaybeInvalidPPN<Meta>

fn cmp(&self, other: &MaybeInvalidPPN<Meta>) -> 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<Meta: PartialEq + VmMeta> PartialEq for MaybeInvalidPPN<Meta>

fn eq(&self, other: &MaybeInvalidPPN<Meta>) -> 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<Meta: PartialOrd + VmMeta> PartialOrd for MaybeInvalidPPN<Meta>

fn partial_cmp(&self, other: &MaybeInvalidPPN<Meta>) -> 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.
