Memcached-GLib

GLib wrapper around libMemcached.

using GLib;
using GMemcached;

var context = new Context.from_configuration ("--SERVER=localhost");

context.@set ("some_key", "some value".data, TimeSpan.HOUR);

var @value = context.@get ("some_key");

Features

• handle status code properly with error domains
• synchronous and asynchronous APIs
• closures for callback API (eg. dump, fetch_execute)
• express expiration with GLib.TimeSpan
• lookup and get_or_compute utilities

Extensions

If a key is missing in the cache, get calls will raise an error. To provide a default value, use the lookup utilities.

var @value = cache.lookup ("some_key") ?? "default value".data;

The get_or_compute utilities makes it comfortable to compute a default value when a key is missing in the cache. The computed value is assigned to the key and returned.

var @value = cache.get_or_compute ("key", (out expiration) => {
  expiration = 15 * TimeSpan.MINUTE;
  return new uint8[1024];
});

Cache pool

It is recommended to use the context in combination of a resource pool like the one provided by Bump.

using Bump;
using GLib;
using GMemcached;

var cache_pool = new ResourcePool<Context> ();

cache_pool.construct_properties = {
    Parameter () {name = "configuration", @value = "--SERVER=localhost"}
};

cache_pool.execute ((cache) => {
  cache.@get ("some_key")
});
