Trait sgx_rand::Rand

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

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:

• Integers (i32, u32, isize, usize, etc.): Uniformly distributed over all values of the type.
• char: Uniformly distributed over all Unicode scalar values, i.e. all code points in the range 0...0x10_FFFF, except for the range 0xD800...0xDFFF (the surrogate code points). This includes unassigned/reserved code points.
• bool: Generates false or true, each with probability 0.5.
• Floating point types (f32 and f64): Uniformly distributed in the half-open range [0, 1). (The Open01, Closed01, Exp1, and StandardNormal wrapper types produce floating point numbers with alternative ranges or distributions.)

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

• Tuples and arrays: Each element of the tuple or array is generated independently, using its own Rand implementation.
• Option<T>: Returns None with probability 0.5; otherwise generates a random T and returns Some(T).

Required Methods

fn rand<R: Rng>(rng: &mut R) -> Self

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