Object Cache

Build Version License: MIT

  • A simple cache util that takes any object reference and caches it in memory or in a file.
  • This crate uses Sqlite db to store objects.
  • It converts the object into JSON format and stores it for the given key.
  • The reverse happens when you retrieve the object.


async fn sample(){
    // build Cache with name (Could be In memory or File based cache)
    let cache = Cache::build(true, "obj_cache").await;

    let data = TestStruct {
        name: "dinesh".to_owned(),
        email: "dinesh.nuke.mars@gmail.com".to_owned(),
        ph_no: 9999999999u64,

    // pass key and object
    cache.save_obj("TestData", &data).await.unwrap();

    // visualize the data

    // get object anywhere in the project using key
    let cached_data: TestStruct = cache.get_obj("TestData").await.unwrap();

Main Functions

Cache {
    pub async fn build(in_memory: bool, cache_file_name: &str) -> Self 
    pub async fn save_obj<T>(&self, key: &str, obj: &T) -> Result<(), CacheError
    pub async fn save_obj_if_not_exist<T>(&self, key: &str, obj: &T) -> Result<(), CacheError
    pub async fn get_obj<T>(&self, key: &str) -> Result<T, CacheError
    pub async fn get_all_objs(&self) -> Result<Vec<CacheData>, CacheError> 
    pub async fn pretty_print_all_cache(&self) 
    pub async fn clear_cache(&self)
