Struct chalk_solve::rust_ir::FnDefDatum

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>>
