Trait Implementations

impl<T: Clone, L: Clone> Clone for ParameterKind<T, L>

fn clone(&self) -> ParameterKind<T, L>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Copy, L: Copy> Copy for ParameterKind<T, L>

impl<T: Debug, L: Debug> Debug for ParameterKind<T, L>

fn fmt(&self, fmt: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl<T: Eq, L: Eq> Eq for ParameterKind<T, L>

impl<I: Interner, TI: TargetInterner<I>, T, L> Fold<I, TI> for ParameterKind<T, L> where
    T: Fold<I, TI>,
    L: Fold<I, TI>, 

type Result = ParameterKind<T::Result, L::Result>

The type of value that will be produced once folding is done. Typically this is Self, unless Self contains borrowed values, in which case owned values are produced (for example, one can fold over a &T value where T: Fold, in which case you get back a T, not a &T).

fn fold_with<'i>(
    &self,
    folder: &mut dyn Folder<'i, I, TI>,
    outer_binder: DebruijnIndex
) -> Fallible<Self::Result> where
    I: 'i,
    TI: 'i, 

Apply the given folder folder to self; binders is the number of binders that are in scope when beginning the folder. Typically binders starts as 0, but is adjusted when we encounter Binders<T> in the IR or other similar constructs.

impl<T: Hash, L: Hash> Hash for ParameterKind<T, L>

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: Ord, L: Ord> Ord for ParameterKind<T, L>

fn cmp(&self, other: &ParameterKind<T, L>) -> 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: PartialEq, L: PartialEq> PartialEq<ParameterKind<T, L>> for ParameterKind<T, L>

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

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

fn ne(&self, other: &ParameterKind<T, L>) -> bool

This method tests for !=.

impl<T: PartialOrd, L: PartialOrd> PartialOrd<ParameterKind<T, L>> for ParameterKind<T, L>

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

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

fn lt(&self, other: &ParameterKind<T, L>) -> bool

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

fn le(&self, other: &ParameterKind<T, L>) -> bool

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

fn gt(&self, other: &ParameterKind<T, L>) -> bool

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

fn ge(&self, other: &ParameterKind<T, L>) -> bool

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

impl<I: Interner, T, L> Visit<I> for ParameterKind<T, L> where
    T: Visit<I>,
    L: Visit<I>, 

fn visit_with<'i, R: VisitResult>(
    &self,
    visitor: &mut dyn Visitor<'i, I, Result = R>,
    outer_binder: DebruijnIndex
) -> R where
    I: 'i, 

Apply the given visitor visitor to self; binders is the number of binders that are in scope when beginning the visitor. Typically binders starts as 0, but is adjusted when we encounter Binders<T> in the IR or other similar constructs.
