Implementations

impl CacheService

pub fn new(cfg: &ApplicationConfig) -> Self

pub fn new_saved(cfg: &ApplicationConfig) -> Self

pub async fn set_string(&self, k: &str, v: &str) -> Result<String>

pub async fn get_string(&self, k: &str) -> Result<String>

pub async fn del_string(&self, k: &str) -> Result<String>

pub async fn set_json<T>(&self, k: &str, v: &T) -> Result<String>

where T: Serialize + Sync,

pub async fn get_json<T>(&self, k: &str) -> Result<T>

where T: DeserializeOwned + Sync,

pub async fn set_string_ex( &self, k: &str, v: &str, ex: Option<Duration>, ) -> Result<String>

pub async fn set_string_ex_nx( &self, k: &str, v: &str, ex: Option<Duration>, ) -> Result<bool>

原子操作：仅当 key 不存在时设置值并设置过期时间 返回 true 表示设置成功（key 原本不存在），false 表示设置失败（key 已存在）

pub async fn ttl(&self, k: &str) -> Result<i64>
