For Rust we recommend the use of the memcached-rs client library. Since version 0.4 it supports SASL authentication and can be used to connect to MemCachier.
Using memcached-rs requires the MEMCACHIER_SERVERS, MEMCACHIER_USERNAME and MEMCACHIER_PASSWORD environment variables. The values for these variables are listed on your cache overview page.
The setup looks as follows:
extern crate memcached;
use std::env;
use memcached::proto::{Operation, ProtoType};
use memcached::Client;
fn main() {
let servers = env::var("MEMCACHIER_SERVERS").unwrap();
let username = env::var("MEMCACHIER_USERNAME").unwrap();
let password = env::var("MEMCACHIER_PASSWORD").unwrap();
let mut client = Client::connect_sasl(servers.split(',').map(|s| format!("{}{}", "tcp://", s))
.map(|s| (s, 1))
.collect::<Vec<(String, usize)>>()
.as_slice(),
ProtoType::Binary,
&username, &password).unwrap();
client.set(b"hello", b"MemCachier", 0xdeadbeef, 2).unwrap();
let (value, flags) = client.get(b"hello").unwrap();
println!("Got: {}", std::str::from_utf8(&value).unwrap());
assert_eq!(&value[..], b"MemCachier");
assert_eq!(flags, 0xdeadbeef);
}
