Struct ViaLink 

pub struct ViaLink {
    pub outer_alias: String,
    pub link_name: String,
}

An unresolved link traversal on a projection, e.g. orders: u.orders { total } (block) or the parent side of a scalar path. Carried on NestedQuery/NestedProjection so the planner stays catalog-pure; the executor resolves it against the persistent catalog at query time (the correlation columns and child table are not known until then).

Fields

outer_alias: String

The outer scan alias the link hangs off (u in u.orders).

link_name: String

The declared link name (orders).
