Struct chalk_ir::TraitId

pub struct TraitId<I: Interner>(pub I::DefId);

The id of a trait definition; could be used to load the trait datum by invoking the trait_datum method.

Trait Implementations

impl<I: Clone + Interner> Clone for TraitId<I> where
    I::DefId: Clone, 

pub fn clone(&self) -> TraitId<I>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I: Copy + Interner> Copy for TraitId<I> where
    I::DefId: Copy, 

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

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

Formats the value using the given formatter.

impl<I: Eq + Interner> Eq for TraitId<I> where
    I::DefId: Eq, 

impl<I: Interner> Fold<I> for TraitId<I>

type Result = TraitId<I>

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).

pub fn fold_with<'i>(
    self,
    _folder: &mut dyn Folder<'i, I>,
    _outer_binder: DebruijnIndex
) -> Fallible<Self::Result> where
    I: '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: Hash + Interner> Hash for TraitId<I> where
    I::DefId: Hash, 

pub fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

pub 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 TraitId<I> where
    I::DefId: Ord, 

pub fn cmp(&self, other: &TraitId<I>) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl<I: PartialEq + Interner> PartialEq<TraitId<I>> for TraitId<I> where
    I::DefId: PartialEq, 

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

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

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

This method tests for !=.

impl<I: PartialOrd + Interner> PartialOrd<TraitId<I>> for TraitId<I> where
    I::DefId: PartialOrd, 

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

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

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

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

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

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

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

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

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

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

impl<I: Interner> StructuralEq for TraitId<I>

impl<I: Interner> StructuralPartialEq for TraitId<I>

impl<I: Interner> Visit<I> for TraitId<I>

pub fn visit_with<'i, B>(
    &self,
    _visitor: &mut dyn Visitor<'i, I, BreakTy = B>,
    _outer_binder: DebruijnIndex
) -> ControlFlow<B> 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.

impl<I: Interner> Zip<I> for TraitId<I>

pub fn zip_with<'i, Z: Zipper<'i, I>>(
    _zipper: &mut Z,
    _variance: Variance,
    a: &Self,
    b: &Self
) -> Fallible<()> where
    I: 'i, 

Uses the zipper to walk through two values, ensuring that they match.
