impl<I: Interner> CastTo<Parameter<I>> for Ty<I>

fn cast_to(self, interner: &I) -> Parameter<I>

impl<I: Interner> CastTo<Parameter<I>> for Lifetime<I>

fn cast_to(self, interner: &I) -> Parameter<I>

impl<I: Interner> CastTo<Parameter<I>> for Parameter<I>

fn cast_to(self, _interner: &I) -> Parameter<I>

impl<I: Clone + Interner> Clone for Parameter<I> where
    I::InternedParameter: Clone, 

fn clone(&self) -> Parameter<I>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I: Copy + Interner> Copy for Parameter<I> where
    I::InternedParameter: Copy, 

impl<I: Interner> Debug for Parameter<I>

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

Formats the value using the given formatter.

impl<I: Eq + Interner> Eq for Parameter<I> where
    I::InternedParameter: Eq, 

impl<I: Interner, TI: TargetInterner<I>> Fold<I, TI> for Parameter<I>

type Result = Parameter<TI>

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<I: Interner> HasInterner for Parameter<I>

type Interner = I

impl<I: Hash + Interner> Hash for Parameter<I> where
    I::InternedParameter: Hash, 

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<I: Ord + Interner> Ord for Parameter<I> where
    I::InternedParameter: Ord, 

fn cmp(&self, other: &Parameter<I>) -> 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.

    I::InternedParameter: PartialEq, 

fn eq(&self, other: &Parameter<I>) -> bool

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

fn ne(&self, other: &Parameter<I>) -> bool

This method tests for !=.

    I::InternedParameter: PartialOrd, 

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

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

fn lt(&self, other: &Parameter<I>) -> bool

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

fn le(&self, other: &Parameter<I>) -> bool

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

fn gt(&self, other: &Parameter<I>) -> bool

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

fn ge(&self, other: &Parameter<I>) -> bool

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