Enum 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.

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].

None

Generate floats in the range [0.0, 1.0].

Trait Implementations

impl Clone for Max

fn clone(&self) -> Max

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Max

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Max

fn eq(&self, other: &Max) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Max

fn partial_cmp(&self, other: &Max) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
