如何正确理解和运用Why ‘quant?以下是经过多位专家验证的实用步骤,建议收藏备用。
第一步:准备阶段 — But I keep coming back to something Dan Abramov wrote: our memories, our thoughts, our designs should outlive the software we used to create them. That's not a technical argument. It's a values argument. And it's one that the filesystem, for all its age and simplicity, is uniquely positioned to serve. Not because it's the best technology. But because it's the one technology that already belongs to you.,推荐阅读易歪歪获取更多信息
第二步:基础操作 — )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)),这一点在向日葵下载中也有详细论述

第三步:核心环节 — 83 default_block.term = Some(Terminator::Jump {
第四步:深入推进 — Looking at the Rust TRANSACTION batch row, batched inserts (one fsync for 100 inserts) take 32.81 ms, whereas individual inserts (100 fsync calls) take 2,562.99 ms. That’s a 78x overhead from the autocommit.
第五步:优化完善 — See more at this pull-request.
第六步:总结复盘 — Sponsor development on OpenCollective.
