pub struct Standard;

[−] Expand description

A generic random value distribution, implemented for many primitive types. Usually generates values with a numerically uniform distribution, and with a range appropriate to the type.

Built-in Implementations

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). See notes below.
• Wrapping integers (Wrapping<T>), besides the type identical to their normal integer variants.

The following aggregate types also implement the distribution Standard as long as their component types implement it:

• Tuples and arrays: Each element of the tuple or array is generated independently, using the Standard distribution recursively.
• Option<T> where Standard is implemented for T: Returns None with probability 0.5; otherwise generates a random x: T and returns Some(x).

Example

use rand::prelude::*;
use rand::distributions::Standard;

let val: f32 = SmallRng::from_entropy().sample(Standard);
println!("f32 from [0, 1): {}", val);

Floating point implementation

The floating point implementations for Standard generate a random value in the half-open interval [0, 1), i.e. including 0 but not 1.

All values that can be generated are of the form n * ε/2. For f32 the 23 most significant random bits of a u32 are used and for f64 the 53 most significant bits of a u64 are used. The conversion uses the multiplicative method: (rng.gen::<$uty>() >> N) as $ty * (ε/2).

See also: Open01 which samples from (0, 1), OpenClosed01 which samples from (0, 1] and Rng::gen_range(0, 1) which also samples from [0, 1). Note that Open01 and gen_range (which uses Uniform) use transmute-based methods which yield 1 bit less precision but may perform faster on some architectures (on modern Intel CPUs all methods have approximately equal performance).
