1. in Cargo.toml define your library [lib] name = "mylib" path = "src/lib.rs" 2. create a file /src/lib.rs with the below content: pub fn foo() { println!("Hallo, Rust library here!") } 3. in your /src/main.rs use it like: use mylib::*; foo();

## If you have multiple libraries call in your rust code ``` use libs::customer::*; use libs::order::*; ``` ## Cargo.toml ```toml [lib] name = "libs" path = "src/libs.rs" ``` ### /src/libs.rs ``` pub mod customer; pub mod order; ``` ## /src/customer.rs ```rust pub async fn foo() { println!("Hallo, Rust library here!") } ``` ## /src/order.rs ```rust pub async fn foo2() { println!("Hallo, Rust library here!") } ``` ## Structure ```txt src ├── customer.rs ├── libs.rs ├── main.rs └── order.rs ``` 26.03.21
