let mut i32cache = Cache::::new();
// expiresinsecs: 0 -> expires immediate
let v1 = i32cache.fetch("v1", 10, || 1);
assert_eq!(v1, &1);
let mut stringcache = Cache::::new();
let v1 = stringcache.fetch("v1", 10, || "1".tostring());
asserteq!(v1, "1");
```
- async cache
```rust
use mem_cache::{AsyncCache};
let mut i32cache = AsyncCache::::new();
// expiresinsecs: 0 -> expires immediate
let v1 = i32cache.fetch("v1", 10, || Box::pin(async {
Ok(1)
})).await?;
assert_eq!(v1, &1);
let mut stringcache = AsyncCache::::new();
let v1 = stringcache.fetch("v1", 10, || Box::pin(async {
Ok("1".tostring())
})).await?;
asserteq!(v1, "1");
