Struct ColumnarGraphMapping

Source 
pub struct ColumnarGraphMapping<VMap, EMap> { /* private fields */ }
Expand description

A graph mapping backed by columns.

That is, the data of the graph mapping is defined by two columns. The mapping can be between arbitrary graphs with compatible vertex and edge types.
