Detailed explanation of the structure and module path of the Rust standard library

In Rust, the standard library provides a core set of features to help developers perform common programming tasks. When using these features, we need to reference them through specific module paths. Below, we will introduce the structure of the Rust standard library in detail and provide the correspondingusepath.

Rust Standard Library Module Path

1. Core primitive type

Basic numeric types, boolean types, characters and string slices, etc. usually do not require additionalusestatements, because they are a basic component of the Rust language.

2. Collection Type

vector(Vec<T>）

use std::vec::Vec;

String (String）

// It usually does not require explicit import String，Because it's in prelude middle

Hash mapping (HashMap<K, V>) and hash collections (HashSet<T>）

use std::collections::HashMap;
use std::collections::HashSet;

Binary heap (BinaryHeap<T>）

use std::collections::BinaryHeap;

3. Error handling

Result<T, E>andOption<T>

// These two types usually do not require explicit import，Because they are prelude middle

4. I/O operations and file systems

Read and write files

use std::fs::File;
use std::io::Read;
use std::io::Write;

Buffer

use std::io::BufReader;
use std::io::BufWriter;

Standard input/output/Error stream

use std::io::{self, stdin, stdout, stderr};

Path operation

use std::path::{Path, PathBuf};

5. Concurrent and asynchronous programming

Thread

use std::thread;

Mutex and read and write locks

use std::sync::Mutex;
use std::sync::RwLock;

Conditional variables

use std::sync::Condvar;

Atomic Type

use std::sync::atomic::{AtomicUsize, Ordering};
// Import other atomic types as needed，like AtomicBool, AtomicIsize wait

6. Network (basic functions, advanced functions are usually in external libraries)

TCP/UDP

use std::net::{TcpListener, TcpStream, UdpSocket};

7. Other practical functions

Time processing

use std::time::{Duration, Instant, SystemTime};

Random number generation

// The standard library does not contain random number generators, and external libraries such as rand are usually used.

Environment variable processing

use std::env;

Command line parameter analysis

use std::env::args;

Please note that as Rust develops, the specific structure of the standard library anduseThe path may change. To obtain the most accurate information, it is recommended to consult Rust's official documentation or use Rust's document generation toolrustdoc。

Additionally, while the Rust standard library provides many core features, developers often rely on rich third-party libraries and frameworks for more complex or specific tasks (such as advanced network programming, web development, GUI development, etc.). These libraries and frameworks can be accessed through Rust's package managercargoEasily add to your project.

Note that this path tree is a simplified representation and does not contain all modules and types from the standard library. Additionally, some modules and types may be in deeper nesting, but for brevity only the directly related paths are shown here.

This path tree can be used as a reference to help you better understand the relationship between the structure and modules of the Rust standard library. However, for the most accurate and up-to-date information, it is recommended to consult Rust's official documentation or use itrustdocTools generate local documents.
