How to Create an Own Crate

I. develop the crate

Step 1: create the default crate

```bash mkdir lib-hello && cd lib-hello

this is Crate Root Path

cargo init --name hello_exercism --lib ```

Step 2: develop the crate source and test codes

• Go to Crate Root Path bash vi Cargo.toml vi src/lib.rs mkdir tests touch tests/u_hello.rs vi tests/u_hello.rs touch tests/i_hello.rs vi tests/i_hello.rs cargo test

  Step 3: develop the example codes

• Go to Crate Root Path bash mkdir examples touch examples/u_hello.rs vi examples/u_hello.rs cargo run --example u_hello touch examples/i_hello.rs vi examples/i_hello.rs cargo run --example i_hello

II. use the crate 'hello_exercism'

Step 1: create the default Bin

```bash mkdir bin-hello && cd bin-hello

this is Bin Root Path

cargo init --name bin-hello --bin ```

Step 2: configure the file Cargo.toml

• Go to Bin Root Path bash echo 'hello_exercism = "0.3.5"' >> Cargo.toml

  Step 3: edit the rust file main.rs

• Go to Bin Root Path ```rust // vi src/main.rs use hello_exercism;

fn main () { println!("{}",helloexercism::hello()); asserteq!("Hello, World!", hello_exercism::hello()); } ```

Step 4: run the Bin program

• Go to Bin Root Path bash cargo run main

III. create the crate 'hello_exercism' doc in local version

• Go to Crate Root Path bash cargo doc --open --package hello_exercism

IV. create the crate 'hello_exercism' doc in server version

• github.com >> >> Setting >> Options >> GitHub Pages >> (INFO...)
• Go to Crate Root Path bash mkdir <REPOSITORY>/docs/<PROJECT_NAME> cargo doc cp -rf target/doc/.  <REPOSITORY>/docs/<PROJECT_NAME>/.
• Example:
• Go to Crate Root Path bash mkdir -p ../../docs/hello-world cargo doc cp -rf target/doc/. ../../docs/hello-world/
