[crate_type = "lib"]-将生成Rust库。由于库可以以多种形式显示自身，因此关于生成的确切内容，这是一个不明确的概念。此通用lib选项的目的是生成“编译器推荐”样式的库。rustc将始终可以使用输出库。但是库的实际类型可能会不时地改变。其余的输出类型都是不同风格的库，lib类型可以被看作其中一个的别名（但是实际的类型是

The issue was caused by a new impl (implementation) ofFromIteratoradded to Box<str>, which had a knock-on impact on Rust code that infers type. Type inference occurs when the compiler deduces the type of a variable by inspecting the value that is assigned to it...

具体来说就是,即使 rustc 很死板无法原生接受某种语义表达,我们也要把这种表达提炼出模式,把模式包装成安全 api,内部开 unsafe,对外有编译期检查。 举个例子: 当前的 NLL borrow checker 有一个最经典的误报—— sum type 条件借用,即 NLL case#3:https://rust-lang.github.io/rfcs/2094-nll.htmlproblem-...

I just learned the hard way (i.e. after lots of scratching my head) that the crate_type attribute is entirely ignored when Cargo is used. This is hinted at in https://doc.rust-lang.org/nightly/reference/linkage.html, but only if you know that cargo always passes --crate-type. The ...
