Dynamic dispatch vs static dispatch
WebDec 5, 2013 · The idea is to find cases of dynamic dispatch where the actual type at a given call site can always to proven to be known at compile time, and specialize those call sites to dispatch statically. This carries the promise of making virtual calls as fast as static dispatch in some special cases. WebSo you could be comparing dynamic dispatch vs a single return. Note that the compiler was able to do these massive optimizations since the enum form (static dispatch) allows for inlining. Often the major overhead of dynamic dispatch isn't calling the function, it's the optimizations that couldn't be performed due to lack of inlining.

WebMultiple dispatch or multimethods is a feature of some programming languages in which a function or method can be dynamically dispatched based on the run-time (dynamic) type or, in the more general case, some other attribute of more than one of its arguments. This is a generalization of single-dispatch polymorphism where a function or method call is … In computer science, dynamic dispatch is the process of selecting which implementation of a polymorphic operation (method or function) to call at run time. It is commonly employed in, and considered a prime characteristic of, object-oriented programming (OOP) languages and systems. Object-oriented systems model a problem as a set of interacting objects that enact operations referred to by name. Polymorphism is the phenomenon wherein somewhat interchangeable obj…
WebAlso dynamic dispatch has more of an OO flavor to it... it's the mechanism behind polymorphism, in which a reference to an object might point to one of multiple implementations. Dynamic dispatch decides at runtime which one to actually run. By contrast, late binding would be dropping in whole new methods that weren't there at … WebThere are two major forms of dispatch: static dispatch and dynamic dispatch. While Rust favors static dispatch, it also supports dynamic dispatch through a mechanism called ‘trait objects’. Background For the rest of this chapter, we’ll need a trait and some implementations.
