Struct rustc_middle::ty::UpvarId

pub struct UpvarId {
    pub var_path: UpvarPath,
    pub closure_expr_id: LocalDefId,
}

Upvars do not get their own NodeId. Instead, we use the pair of the original var ID (that is, the root variable that is referenced by the upvar) and the ID of the closure expression.

Fields

var_path: UpvarPath

closure_expr_id: LocalDefId
