Struct rustc::ty::UpvarId

pub struct UpvarId {
    pub var_id: NodeId,
    pub closure_expr_id: NodeId,
}

Unstable (rustc_private)

Upvars do not get their own node-id. 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_id: NodeId
