Trait rand::Rand [] [src]

pub trait Rand {
    fn rand<R>(rng: &mut R) -> Self
    where
        R: Rng
; }

A type that can be randomly generated using an Rng.

Built-in Implementations

This crate implements Rand for various primitive types. Assuming the provided Rng is well-behaved, these implementations generate values with the following ranges and distributions:

The following aggregate types also implement Rand as long as their component types implement it:

Required Methods

Generates a random instance of this type using the specified source of randomness.
