rustHow to read YAML file in Rust

Reading YAML files in Rust is easy with the serde_yaml crate. To read a YAML file, first add the crate to your Cargo.toml file:

[dependencies]
serde_yaml = "1.0"

Then, use the from_reader method to read the YAML file into a Rust data structure:

use std::fs::File;
use serde_yaml;

let file = File::open("example.yaml")?;
let data: serde_yaml::Value = serde_yaml::from_reader(file)?;

The serde_yaml::Value type is a generic type that can represent any valid YAML data structure. You can then use the as_* methods to convert the Value into the desired Rust type.
