In this tutorial, you will learn about Rust Cargo. We cover key concepts, practical examples, and best practices to help you master this topic.
Rust Cargo manages packages with Cargo.toml configuration, crates.io dependencies, build scripts, and workspace organization for multi-crate projects.
What You'll Learn
- Cargo.toml structure
- Adding dependencies
- Build configurations
- Workspaces
Why It Matters
Cargo is essential for Rust development. DodaZIP uses Cargo for dependency management and builds.
Real-World Use
Package management, build automation, project scaffolding, workspace organization.
[package]
name = "myapp"
version = "0.1.0"
edition = "2021"
[dependencies]
serde = { version = "1.0", features = ["derive"] }
serde_json = "1.0"
tokio = { version = "1.0", features = ["full"] }
reqwest = { version = "0.11", features = ["json"] }
[dev-dependencies]
criterion = "0.5"
[profile.release]
opt-level = 3
lto = true
// Using dependencies
use serde::{Serialize, Deserialize};
#[derive(Serialize, Deserialize, Debug)]
struct User {
name: String,
age: u8,
}
fn main() {
let user = User { name: "Alice".into(), age: 30 };
let json = serde_json::to_string(&user).unwrap();
println!("{}", json);
}
