Struct rustc::ty::UpvarId
[−]
[src]
pub struct UpvarId { pub var_id: NodeId, pub closure_expr_id: NodeId, }
🔬 This is a nightly-only experimental API. (
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.
