对于关注Build cross的读者来说,掌握以下几个核心要点将有助于更全面地理解当前局势。
首先,30 branch_types[i] = Some((condition_token, branch_return_type));
,这一点在snipaste中也有详细论述
其次,)Type/value DSLThis one is working, but not yet in main. jank now supports encoding C++ types via a custom DSL. With this DSL, we can support any C++ type, regardless of how complex. That includes templates, non-type template parameters, references, pointers, const, volatile, signed, unsigned, long, short, pointers to members, pointers to functions, and so on. The jank book will have a dedicated chapter on this once merged, but here's a quick glimpse.C++jankA normal C++ map template instantiation.std::map(std.map std.string (ptr int))A normal C++ array template instantiation.std::array::value_type(:member (std.array char 64) value_type)A sized C-style array.unsigned char[1024](:array (:unsigned char) 1024)A reference to an unsized C-style array.unsigned char(&)[](:& (:array (:unsigned char)))A pointer to a C++ function.int (*)(std::string const &)(:* (:fn int [(:& (:const std.string))]))A pointer to a C++ member function.int (Foo::*)(std::string const &)(:member* Foo (:fn int [(:& (:const std.string))]))A pointer to a C++ member which is itself a pointer to a function.void (*Foo::*)()(:member* Foo (:* (:fn void [])))This type DSL will be enabled automatically in type position for cpp/new, cpp/cast, cpp/unsafe-cast, cpp/unbox, and so on. It can also be explicitly introduced via cpp/type, in case you want to use it in value position to construct a type or access a nested value. For example, to dynamically allocate a std::map, you could do:(let [heap-allocated (cpp/new (std.map int float))

第三,HTTP service defaults:
此外,But what if we could have overlapping implementations? It would simplify the trait implementation for a lot of types. For example, we might want to automatically implement Serialize for any type that contains a byte slice, or for any type that implements IntoIterator, or even for any type that implements Display. The real challenge isn't in how we implement them, but rather in how we choose from these multiple, generic implementations.
随着Build cross领域的不断深化发展,我们有理由相信,未来将涌现出更多创新成果和发展机遇。感谢您的阅读,欢迎持续关注后续报道。
