LRU Cache

Install with component(1):

$ component install yields/lru-cache

Initialize Cache with opts

• .max max items.

Set key, val. key may be an object.

an optional ttl may be given, if omitted the global ttl is used.

var c = cache();
c.set('a', 'b', '5ms');

Get key's value, and promote it.

Check if key exists.

Remove key

Set max vals and remove items if necessary.

Set ttl for all values, you can override this at a value level.

var c = cache({ ttl: '2ms' });
c.ttl('5ms');
c.set('a', 'b', '1ms');
c.set('d', 'c'); // => 5ms

by default ttl is 0, which means no values will expire.

Get a cloned cache with { key: val } structure.

Manually promote key.
