Struct ImplAssocItem 

pub struct ImplAssocItem {
    pub name: Option<Symbol>,
    pub decl_def_id: DefId,
    pub required_impl_exprs: Vec<ImplExpr>,
    pub value: ImplAssocItemValue,
}

An associated item in a trait impl. This can be an item provided by the trait impl, or an item that reuses the trait decl default value.

Fields

name: Option<Symbol>

This is None for RPTITs.

decl_def_id: DefId

The definition of the item from the trait declaration. This is an AssocTy, AssocFn or AssocConst.

required_impl_exprs: Vec<ImplExpr>

The ImplExprs required to satisfy the predicates on the associated type. E.g.:

trait Foo {
    type Type<T>: Clone,
}
impl Foo for () {
    type Type<T>: Arc<T>; // would supply an `ImplExpr` for `Arc<T>: Clone`.
}

Empty if this item is an associated const or fn.

value: ImplAssocItemValue

The value of the implemented item.
