NEAR-RNG
This is a fork of tiny-rng https://github.com/JohnBSmith/tiny-rng to work with smart contract of the NEAR protocol to minimize the binary size of the wasm
Warning: Not cryptographically secure.
Examples:
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;
}
}
