1//! [ArceOS](https://github.com/arceos-org/arceos) network module.
2//!
3//! It provides unified networking primitives for TCP/UDP communication
4//! using various underlying network stacks. Currently, only [smoltcp] is
5//! supported.
6//!
7//! # Organization
8//!
9//! - [`TcpSocket`]: A TCP socket that provides POSIX-like APIs.
10//! - [`UdpSocket`]: A UDP socket that provides POSIX-like APIs.
11//! - [`dns_query`]: Function for DNS query.
12//!
13//! # Cargo Features
14//!
15//! - `smoltcp`: Use [smoltcp] as the underlying network stack. This is enabled
16//!   by default.
17//!
