NEAR-RNG

这是一个基于 tiny-rng https://github.com/JohnBSmith/tiny-rng 的分支，用于与 NEAR 协议的智能合约一起工作，以最小化 wasm 的二进制大小

示例

use near_sdk::borsh::{self, BorshDeserialize, BorshSerialize};
use near_sdk::{env, near_bindgen};
use near_rng::{Rng};

near_sdk::setup_alloc!();

#[near_bindgen]
#[derive(Default, BorshDeserialize, BorshSerialize)]
pub struct Counter {
    val: i32,
}

#[near_bindgen]
impl Counter {
  pub fn increment(&mut self) {
    let mut rng = Rng::new(&env::random_seed());
    let value = rng.rand_range_i32(0, 20);
    self.val += value;
  }
}
