uuid from string rust

To parse a UUID from a string in Rust, you can use the uuid crate. Here's an example of how to do it:

use uuid::Uuid;

fn main() {
    let uuid_string = "550e8400-e29b-41d4-a716-446655440000";
    let uuid = Uuid::parse_str(uuid_string).unwrap();
    println!("Parsed UUID: {:?}", uuid);
}

In this example, we first import the Uuid type from the uuid crate. Then, we define a string uuid_string that contains the UUID in the format "550e8400-e29b-41d4-a716-446655440000". We use the parse_str method of Uuid to parse the string and obtain a Uuid instance. Finally, we print the parsed UUID.

Please note that you need to add the uuid crate to your Cargo.toml file in order to use it. You can add it under the [dependencies] section like this:

[dependencies]
uuid = "0.8.2"

Make sure to replace the version number with the latest version of the uuid crate.

I hope this helps! Let me know if you have any further questions.
