Struct chalk_ir::InEnvironment [−][src]
pub struct InEnvironment<G: HasInterner> {
pub environment: Environment<G::Interner>,
pub goal: G,
}
Expand description
A goal with an environment to solve it in.
Fields
environment: Environment<G::Interner>
goal: G
Implementations
Creates a new environment/goal pair.
pub fn map<OP, H>(self, op: OP) -> InEnvironment<H> where
OP: FnOnce(G) -> H,
H: HasInterner<Interner = G::Interner>,
pub fn map<OP, H>(self, op: OP) -> InEnvironment<H> where
OP: FnOnce(G) -> H,
H: HasInterner<Interner = G::Interner>,
Maps the goal without touching the environment.

T: HasInterner<Interner = I> + CastTo<U>,
U: HasInterner<Interner = I>,
I: Interner,
impl<T, U, I> CastTo<InEnvironment<U>> for InEnvironment<T> where
T: HasInterner<Interner = I> + CastTo<U>,
U: HasInterner<Interner = I>,
I: Interner,
Cast a value to type T
.
impl<G: HasInterner, _I, _U> Fold<_I> for InEnvironment<G> where
_I: Interner,
G: HasInterner<Interner = _I>,
G: Fold<_I, Result = _U>,
_U: HasInterner<Interner = _I>,
impl<G: HasInterner, _I, _U> Fold<_I> for InEnvironment<G> where
_I: Interner,
G: HasInterner<Interner = _I>,
G: Fold<_I, Result = _U>,
_U: HasInterner<Interner = _I>,
type Result = InEnvironment<_U>
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
). Read more
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. Read more

Shifts this term in one level of binders.
Shifts a term valid at outer_binder
so that it is
valid at the innermost binder. See DebruijnIndex::shifted_in_from
