Struct uuid64rs::Uuid4

pub struct Uuid4(_);

Minimum structure for implementing core trait.

It implements a lot of From and TryFrom traits to allow easy interfacing with most any code and easy conversions between formats.

Implementations

impl Uuid4

pub fn new<'a, TR>(rng: TR) -> Self where
    TR: Into<Option<&'a mut ThreadRng>>, 

Construct a new random instance.

Arguments

• rng - Optional random number generator to save startup overhead when generating lots of new UUIDs or other custom needs.
