Distinguishing Debug and Release Environments It is well known that Debug is the compilation constant that is automatically available when developing in VS, while the code released uses Release. To create different compilation conditions in Debug and Release e…

区分 调试和发布环境 众所周知，Debug 是在开发、在 VS 中时，自动会有的编译常量，而代码发布后则是 Release。 为了在 Debug、Release 环境下出现不同的编译条件。 .NET Core 项目添加条件编译变量，可在 .csproj 中加上 <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|AnyCPU'"> <DefineConstants>AAAA</DefineConstants&…

Parallelism through simple threads Every year, parallelism and concurrency become more important as processors tend to have more and more physical cores. In most languages, writing parallel code is tricky. Very tricky. Not so in Rust, as it has been designed a…

Using the builder pattern Sometimes you need something between the customization of the constructor and the implicitness of the default implementation. Enter the builder pattern, another technique frequently used by the Rust standard library, as it allows a ca…

Using the constructor pattern You may have asked yourself how to idiomatically initialize complex structs in Rust, considering it doesn't have constructors. The answer is simple, there is a constructor, it's just a convention rather than a rule. Rust's standar…

Providing a default implementation Often, when dealing with structures that represent configurations, you don't care about certain values and just want to silently assign them a standard value. Usually, when processing structures that represent configurations,…

Providing a default implementation Often, when dealing with structures that represent configurations, you don't care about certain values and just want to silently assign them a standard value. 通常，当处理表示配置的结构时，你并不关心某些值，只想为其默默分配一个标准值。 Rust 使用 Default::default();…

Using the format! macro format! is a Rust macro that is essentially similar to the usage of String.Format() in C#. There is an additional way to combine strings, which can also be used to combine them with other data types, such as numbers. It provides another…

Using the format! macro format! 是一个 rust 宏，跟 C# 的 String.Format() 用法基本一致。 There is an additional way to combine strings, which can also be used to combine them with other data types, such as numbers. 能够以另一种方式去组合字符串，也可以组合不同的数据类型，例如数字。 其定义如下： #[macro_export] #[s…
