Study Notes
- The Rust Standard Library offers a number of primitive types and library-defined operations on them.
- These are available to all crates by default.
- Implicit methods on primitive types are documented here.
- The standard library defines The Rust Prelude, a small collection of traits that are imported into every module of every crate.
- The standard library exports a number of standard macros.
- The standard library provides a variety of data types, functions, and abstractions to make working with Rust code easier.
- Slices can only be handled through pointers, and so come in many flavors.
- The collections module defines maps, sets, linked lists, and other collection types.
- Platform abstractions and I/O are provided in the io, fs, and net modules.
- The thread module contains Rust's threading abstractions.
