A structure representing a mapping pair for a type mapping.
The mapping pair typically contains one FlatType on one side (a or b), and one or multiple FlatTypes on the other side (a or b). If, for example, side a contains one FlatType and b contains two FlatTypes (b0 and b1), that means that if this is a mapping pair of a mapping between two types A and B, when some node X of type A and a node Y of type B connect to each other, then in hardware FlatType b0 and b1 are concatenated onto a.

| std::shared_ptr< Node > cerata::MappingPair::width_a | ( | const OptionalNode & | no_width_increment = {} | ) | const |
Return the total width of the types on side A.
| no_width_increment | In case some flat type doesn't have a width, increment it with this parameter. |

| std::shared_ptr< Node > cerata::MappingPair::width_b | ( | const OptionalNode & | no_width_increment = {} | ) | const |
Return the total width of the types on side B.
| no_width_increment | In case some flat type doesn't have a width, increment it with this parameter. |
