pub struct Identity;Expand description
The identity functor, which implements Functor for any signature.

a: &SemifiniteFunction<K, O>,
) -> IndexedCoproduct<K, SemifiniteFunction<K, O>>
fn map_object( a: &SemifiniteFunction<K, O>, ) -> IndexedCoproduct<K, SemifiniteFunction<K, O>>
Action on objects
Source§fn map_arrow(f: &OpenHypergraph<K, O, A>) -> OpenHypergraph<K, O, A>
fn map_arrow(f: &OpenHypergraph<K, O, A>) -> OpenHypergraph<K, O, A>
Action on arrows

) -> IndexedCoproduct<K, SemifiniteFunction<K, O>>
fn map_object( a: &SemifiniteFunction<K, O>, ) -> IndexedCoproduct<K, SemifiniteFunction<K, O>>
Action on objects
Source§fn map_operations(ops: Operations<K, O, A>) -> OpenHypergraph<K, O, A>
fn map_operations(ops: Operations<K, O, A>) -> OpenHypergraph<K, O, A>
Often, it’s easier to map a list of operations f, g, h into their tensoring F(f) ● F(g) ●
F(h).
This efficiently generalises to the implementation of map_arrow.
fn map_arrow(f: &OpenHypergraph<K, O1, A1>) -> OpenHypergraph<K, O2, A2>
