Usage

```rust use pocketcache::cache::Cache; use pocketcache::time::Expiration;

[derive(Debug)]

struct Data { messages: Vec, }

fn main() { let expiration = Expiration::Hour(3); let mut cache = Cache::::new(expiration);

// set cache.set( "fruit", Data { messages: vec![String::from("peach")], }, );

// get let fruit = cache.get("fruit"); println!("{:#?}", fruit); // Some( Data { messages: { ["peach"] } } )

// delete cache.delete("fruit"); let fruit = cache.get("fruit"); println!("{:#?}", fruit); // None } ```

API

Expiration

```rust use pocketcache::time::Expiration;

let expiration = Expiration::Second(30); // 30ces let expiration = Expiration::Minute(5); // 5min let expiration = Expiration::Hour(3); // 3 hour let expiration = Expiration::Default; // 1 hour ```

Cache

```rust use pocketcache::cache::Cache; use pocketcache::time::Expiration;

let mut cache = Cache::<&str>::new(Expiration::Default); ```

set

rust cache.set("fruit", "banana"); cache.set("vegetable", "carrot"); cache.set("meat", "crab");

get

```rust let mut cache = Cache::<&str>::new(Expiration::Default);

let fruit = cache.get("fruit"); println!("{:#?}", fruit); // None

cache.set("fruit", "banana"); let fruit = cache.get("fruit"); println!("{:#?}", fruit); // Some("banana")

cache.set("fruit", "peach"); let fruit = cache.get("fruit"); println!("{:#?}", fruit); // Some("peach")

// after 1 hour...

let fruit = cache.get("fruit"); println!("{:#?}", fruit); // None ```

delete

```rust cache.set("fruit", "banana"); cache.delete("fruit");

let fruit = cache.get("fruit"); println!("{:#?}", fruit); // None ```

clear

```rust cache.set("fruit", "banana"); cache.set("vegetable", "carrot"); cache.set("meat", "crab"); cache.clear();

println!("{:#?}", cache.get("fruit")); // None println!("{:#?}", cache.get("vegetable")); // None println!("{:#?}", cache.get("meat")); // None ```
