rustHow to write YAML to file in Rust

Writing YAML to file in Rust is easy with the serde_yaml crate.

Example code:

use serde_yaml;

let data = vec![1, 2, 3];

let serialized = serde_yaml::to_string(&data).unwrap();

std::fs::write("data.yaml", serialized).unwrap();

Output example

[1, 2, 3]

Code parts:

1. use serde_yaml; - imports the serde_yaml crate.
2. let data = vec![1, 2, 3]; - creates a vector of data to be serialized.
3. let serialized = serde_yaml::to_string(&data).unwrap(); - serializes the data into a YAML string.
4. std::fs::write("data.yaml", serialized).unwrap(); - writes the serialized data to a file named data.yaml.
