Enum artichoke_backend::extn::stdlib::securerandom::Max

pub enum Max {
    Float(f64),
    Integer(i64),
    None,
}

Max value when generating a random number from a range.

In Ruby, the rand family of functions generate random numbers form within a range. This range is always anchored on the left by zero. The Max enum allows callers to specify the upper bound of the range. If the None variant is given, the default is set to generate floats in the range of [0.0, 1.0).

Variants

Float(f64)

Generate floats in the range [0, max).

If max is less than or equal to zero, the range defaults to floats in [0.0, 1.0].

If max is NaN, an error is returned.

Tuple Fields of Float

0: f64

Integer(i64)

Generate signed integers in the range [0, max).

If max is less than or equal to zero, the range defaults to floats in [0.0, 1.0].

Tuple Fields of Integer

0: i64

None

Generate floats in the range [0.0, 1.0].

Trait Implementations
