async memcached memcached-client

memcached.zig

A memcached client library for Zig, built on std.Io for async I/O. Uses the modern meta protocol for efficient communication.

Features

  • Async I/O via std.Io
  • Connection pooling per server
  • Multi-server support with consistent hashing (rendezvous)
  • Meta protocol (mg, ms, md, ma commands)
  • CAS (compare-and-swap) support
  • TTL and flags support

Example

const std = @import("std");
const memcached = @import("memcached");

pub fn main(init: std.process.Init) !void {
    const allocator = init.gpa;
    const io = init.io;

    var client = try memcached.connect(allocator, io, "localhost:11211");
    defer client.deinit();

    // Set a value
    try client.set("hello", "world", .{ .ttl = 300 });

    // Get a value
    var buf: [1024]u8 = undefined;
    if (try client.get("hello", &buf, .{})) |info| {
        std.debug.print("Value: {s}\n", .{info.value});
    }

    // Increment a counter
    try client.set("counter", "0", .{});
    const val = try client.incr("counter", 1);
    std.debug.print("Counter: {d}\n", .{val});
}

Multi-server

var client = try memcached.Client.init(allocator, io, .{
    .servers = &.{
        "server1:11211",
        "server2:11211",
        "server3:11211",
    },
    .hasher = .rendezvous,
});
defer client.deinit();

Installation

Add memcached.zig as a dependency in your build.zig.zon:

zig fetch --save "git+https://github.com/lalinsky/memcached.zig"

In your build.zig:

const memcached = b.dependency("memcached", .{
    .target = target,
    .optimize = optimize,
});
exe.root_module.addImport("memcached", memcached.module("memcached"));
