QryData could be written in the sense of QryData{ ... frame: .., packet: .., segment:.. }
|
||||
On the one hand, only the actual type of frame/packet/segment would be contained in the resulting struct.
|
||||
So, increased benefit in serialization/cpu time, could result in less data to be serialized, depending on layout.
|
||||
On the other hand, each datagram::type needs to implement traits which would need to be dynamically dispatched by returning any of these types per iso level from a single function each. The result would be a performance decrease.
|
||||
See: https://doc.rust-lang.org/book/ch10-02-traits.html#returning-types-that-implement-traits
|
||||
See: https://doc.rust-lang.org/book/ch17-02-trait-objects.html#trait-objects-perform-dynamic-dispatch
|
||||
Then again, parser logic would be fewer lines + more unified using the latter method. Maybe better optimizable as well? Maybe this is a nice tradeoff?

QryData could be written in the sense of QryData{ ... frame: .., packet: .., segment:.. }
|
||||
On the one hand, only the actual type of frame/packet/segment would be contained in the resulting struct.
|
||||
So, increased benefit in serialization/cpu time, could result in less data to be serialized, depending on layout.
|
||||
On the other hand, each datagram::type needs to implement traits which would need to be dynamically dispatched by returning any of these types per iso level from a single function each. The result would be a performance decrease.
|
||||
See: https://doc.rust-lang.org/book/ch10-02-traits.html#returning-types-that-implement-traits
|
||||
See: https://doc.rust-lang.org/book/ch17-02-trait-objects.html#trait-objects-perform-dynamic-dispatch
|
||||
Then again, parser logic would be fewer lines + more unified using the latter method. Maybe better optimizable as well? Maybe this is a nice tradeoff?
