derive-redis-json

一个使用serde对JSON值进行编码并存储到redis以及从redis检索的derive工具。

示例

Cargo.toml

[dependencies]
derive-redis-json = "0.1.1"

main.rs

use std::sync::Arc;

use anyhow::Result;
use deadpool_redis::{redis::cmd, Pool as RedisPool};
use derive_redis_json::RedisJsonValue;
use serde::{Deserialize, Serialize};

#[derive(Serialize, Deserialize, RedisJsonValue)]
pub struct User {
  pub id: u64,
  pub name: String,
}

pub async fn add_user(
  redis_pool: Arc<RedisPool>,
  user: User,
) -> Result<usize> {
  let mut conn = redis_pool.get().await?;
  let res: usize = cmd("SADD")
    .arg("Users")
    .arg(&user)
    .query_async(&mut conn)
    .await?;

  Ok(res)
}

pub async fn get_users(
  redis_pool: Arc<RedisPool>,
) -> Result<Vec<User>> {
  let mut conn = redis_pool.get().await?;
  let res: Vec<User> = cmd("SMEMBERS").arg("Users").query_async(&mut conn).await?;

  Ok(res)
}
