Rust: What is the difference between UdpSocket and tokio::net::UdpSocket?

UdpSocket — blocking. tokio::UdpSocket — async.

UdpSocket:

• Blocking.
• Blocks thread.
• For sync code.

tokio::UdpSocket:

• Async.
• Non-blocking.
• For async code.

1// Blocking
2use std::net::UdpSocket;
3let socket = UdpSocket::bind("127.0.0.1:8080")?;
4
5// Async
6use tokio::net::UdpSocket;
7let socket = UdpSocket::bind("127.0.0.1:8080").await?;

Key: std for blocking, tokio for async.
