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