What is an "item" in Rust?

The 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.

What is an item and is there a comprehensive list of all the kinds that there are in Rust?
