# UUID
The UUID struct provides a wrapper around the uuid::Uuid type from
the uuid crate. It provides methods for generating new UUIDs
(Universally Unique Identifiers) in version 3, 4, or 5.
# Examples
use uuid::Uuid;
use my_crate::UUID;
let ns = Uuid::parse_str("6ba7b810-9dad-11d1-80b4-00c04fd430c8").unwrap();
let name = "my_name";
let uuid_v3 = UUID::new(3, &ns, name);
let uuid_v4 = UUID::new(4, &ns, name);
let uuid_v5 = UUID::new(5, &ns, name);
assert_eq!(uuid_v3.to_string().is_err(), false);
assert_eq!(uuid_v4.to_string().is_err(), false);
assert_eq!(uuid_v5.to_string().is_err(), false);
# Methods
# new
pub fn new(version: u8, ns: &Uuid, name: &str) -> Self
Generates a new UUID in the specified version. The ns parameter is the
namespace to use for the UUID and must be a valid UUID. The name
parameter is the name to use for the UUID.
# uuid_v3
pub fn uuid_v3(ns: &Uuid, name: &str) -> Self
Generates a new v3 UUID. The ns parameter is the namespace to use for
the UUID and must be a valid UUID. The name parameter is the name to
use for the UUID.
# uuid_v4
pub fn uuid_v4() -> Self
Generates a new v4 UUID.
# uuid_v5
pub fn uuid_v5(ns: &Uuid, name: &str) -> Self
Generates a new v5 UUID. The ns parameter is the namespace to use for
the UUID and must be a valid UUID. The name parameter is the name to
use for the UUID.
# Implementations
# fmt::Display
This implementation of the fmt::Display trait allows instances of
UUID to be printed using the {} formatting placeholder. The write!
macro is used to write the string representation of self.inner to the
provided fmt::Formatter. The fmt::Result type is returned to
indicate whether the operation was successful or not.
