Struct chalk_solve::rust_ir::FnDefDatum [−][src]
pub struct FnDefDatum<I: Interner> {
pub id: FnDefId<I>,
pub sig: FnSig<I>,
pub binders: Binders<FnDefDatumBound<I>>,
}
Expand description
A rust intermediate represention (rust_ir) of a function definition/declaration. For example, in the following rust code:
fn foo<T>() -> i32 where T: Eq;
This would represent the declaration of foo
.
Note this is distinct from a function pointer, which points to a function with a given type signature, whereas this represents a specific function definition.
Fields
id: FnDefId<I>
sig: FnSig<I>
binders: Binders<FnDefDatumBound<I>>
Trait Implementations

Given the following function definition: fn bar<T>() where T: Eq
, generate:
-- Rule WellFormed-Type
forall<T> {
WF(bar<T>) :- WF(T: Eq)
}
-- Rule Implied-Bound-From-Type
forall<T> {
FromEnv(T: Eq) :- FromEnv(bar<T>).
}
forall<T> {
IsFullyVisible(bar<T>) :- IsFullyVisible(T).
}

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. Read more
