Rust 生態系統 Rust 生態系統包含多項工具，以下列出主要工具： • rustc：Rust 編譯器，可將 .rs 檔案轉換成二進位檔和其他中繼格式。 • cargo: the Rust dependency manager and build tool. Cargo knows how to download dependencies, usually hosted on https://crates 料的複雜資料型別。透過「建構工具模式」，我們會以便利函 式逐段建構新值。 請填補缺漏的片段。 enum Language { Rust, Java, Perl, } struct Dependency { name: String, version_expression: String, } /// A representation of a software package. struct dependencies: Vec<Dependency>, language: Option, } impl Package { /// Return a representation of this package as a dependency, for use in /// building other packages. fn as_dependency(&self) -> Dependency

modules it imports, the Julia build, files it includes, or explicit dependencies declared by include_dependency(path) in the module file(s). For file dependencies loaded by include, a change is determined by (fsize) or content (condensed into a hash) is unchanged. For file dependencies loaded by include_dependency a change is determined by examining whether the modification time (mtime) is unchanged, or equal package named X in the main project but potentially to different packages also named X in each dependency. More on this below. Code inclusion is quite straightforward and simple: it evaluates the given
