rustRust YAML parser example

serde_yaml is a Rust library for parsing and serializing YAML. Here is an example of how to parse a YAML string:

use serde_yaml;

let yaml_str = "
name: John
age: 30
";

let data: serde_yaml::Value = serde_yaml::from_str(yaml_str).unwrap();

println!("Name: {}", data["name"].as_str().unwrap());
println!("Age: {}", data["age"].as_i64().unwrap());

This code will ## Output example

Name: John
Age: 30

The code consists of the following parts:

1. use serde_yaml: This imports the serde_yaml library.
2. let yaml_str = ...: This creates a string containing the YAML data.
3. let data: serde_yaml::Value = serde_yaml::from_str(yaml_str).unwrap(): This parses the YAML string and stores the result in a serde_yaml::Value object.
4. println!("Name: {}", data["name"].as_str().unwrap()): This prints the value of the name key as a string.
5. println!("Age: {}", data["age"].as_i64().unwrap()): This prints the value of the age key as an integer.
