Trait Random 

pub trait Random {
    // Required method
    fn random() -> Self;
}

Available on crate features rand-expand and rand only.

可随机生成的类型。

熵源取自 next。各实现的取值语义：

• 整数：取 next() 输出并截断为目标位宽（as 转换）；
• bool：取最低位；
• 浮点（f32 / f64）：[0, 1) 区间内均匀分布。

Feature Requirement

需要启用 "rand-expand" 特性。

Examples

use lib_unknown::rand::{Random, random};

let v: u64 = random();
let _ = v;

Required Methods

fn random() -> Self

生成一个该类型的随机值（语义见 trait 级文档）。

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
