Implementations

impl<G: HasInterner> InEnvironment<G>

pub fn new(environment: &Environment<G::Interner>, goal: G) -> Self

pub fn map<OP, H>(self, op: OP) -> InEnvironment<H> where
    OP: FnOnce(G) -> H,
    H: HasInterner<Interner = G::Interner>, 

Trait Implementations

impl<T, U, I> CastTo<InEnvironment<U>> for InEnvironment<T> where
    T: HasInterner<Interner = I> + CastTo<U>,
    U: HasInterner<Interner = I>,
    I: Interner, 

fn cast_to(self, interner: &U::Interner) -> InEnvironment<U>

impl<G: Clone + HasInterner> Clone for InEnvironment<G> where
    G::Interner: Clone, 

fn clone(&self) -> InEnvironment<G>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<G: Debug + HasInterner> Debug for InEnvironment<G> where
    G::Interner: Debug, 

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

Formats the value using the given formatter.

impl<G: Eq + HasInterner> Eq for InEnvironment<G> where
    G::Interner: Eq, 

impl<G: HasInterner, _I, _U, _TI> Fold<_I, _TI> for InEnvironment<G> where
    _I: Interner,
    G: HasInterner<Interner = _I>,
    G: Fold<_I, _TI, Result = _U>,
    _U: HasInterner<Interner = _TI>,
    _TI: TargetInterner<_I>, 

type Result = InEnvironment<_U>

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<G: HasInterner> HasInterner for InEnvironment<G>

type Interner = G::Interner

impl<G: Hash + HasInterner> Hash for InEnvironment<G> where
    G::Interner: 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<G: PartialEq + HasInterner> PartialEq<InEnvironment<G>> for InEnvironment<G> where
    G::Interner: PartialEq, 

fn eq(&self, other: &InEnvironment<G>) -> bool

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

fn ne(&self, other: &InEnvironment<G>) -> bool

This method tests for !=.

impl<G: HasInterner> StructuralEq for InEnvironment<G>

impl<G: HasInterner> StructuralPartialEq for InEnvironment<G>

impl<G: HasInterner, _I> Visit<_I> for InEnvironment<G> where
    _I: Interner,
    G: HasInterner<Interner = _I>,
    G: 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.

impl<T: HasInterner<Interner = I> + Zip<I>, I: Interner> Zip<I> for InEnvironment<T>

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