is_iterator: bool:指示逃逸闭包是否作为迭代器使用。 can_return: bool:指示逃逸闭包是否有可能被返回。 EscapeDelegate结构体实现了RustLintDelegate trait,是逃逸闭包的检查器。它定义了在代码中遇到逃逸闭包时需要执行的检查逻辑。 在EscapeDelegate中,我们可以定义过程宏用于匹配特定的语法结构,然后针对这些匹配进行代码...

Rust 编译器错误信息所建议的修复方法可以使程序编译成功,但这并不等同于可以使程序编译成功并且最符合要求。 生命周期在编译期进行静态验证 生命周期不能在运行期以任何方式增长、缩短或改变 Rust 借用检查器总是假定所有代码路径都会被执行,然后为变量选择最短的生命周期 ...

cargo check 运行rustc的检查,但在它开始输出代码和优化之前就停止了。这对于开发过程中的错误检查很有用。 cargo build 构建一个库或二进制文件,取决于crate类型。 cargo clippy 运行 Rust linter, Clippy。
