江浔 Result | #Rust(编程语言) 感谢超凡的Enum,Rust异常返回语法吊打了golang直白的二元组。Enum从一个单纯的枚举,成为了一个多态数据容器,这一点弥补了新一代接口-函数绑定模型,即无法枚举子类,也不包含任何数据结构信息的缺憾。一个相当漂亮的创意。之前虽然也用java enum模拟过类似特性,但是终究在语法

Contributor cassidoxa commented Mar 20, 2024 A common convention in Rust when converting from one type to another in a fallible way (i.e., when returning a Result,) is to name the function try_from_* instead of from_*, which is used for infallible conversions (we also see this same...
