[−][src]Struct declarative_dataflow::plan::project::Project
A plan stage projecting its source to only the specified sequence of variables. Throws on unbound variables. Frontends are responsible for ensuring that the source binds all requested variables.
Fields
variables: Vec<u32>
TODO
plan: Box<P>
Plan for the data source.
