Rust 中的 "item" 是什么？
What is an "item" in Rust?
Rust Book makes several references to the word "item", which confers the word a technical meaning in the context of the Rust programming language. For example, see Chapter 07-03:
The way privacy works in Rust is that all items (functions, methods, structs, enums, modules, and constants) are private by default. Items in a parent module can’t use the private items inside child modules, but items in child modules can use the items in their ancestor modules.
什么是项，是否有 Rust 中所有种类的完整列表？
An item is a component of a crate. [...] There are several kinds of items:
- Modules
extern crate declarationsuse declarations- Function definitions
- Type definitions
- Struct definitions
- Enumeration definitions
- Union definitions
- Constant items
- Static items
- Trait definitions
- Implementations
extern blocks
An item is simply any declaration that could appear globally in a program or module, such as a fn, struct, or use.
