Memcachr: A memcached server implementation in Rust

Note: This is mostly intended as a learning project and is not recommended for a production use case.

Currently implemented commands

• get <key>
• set <key> <flags> <expiration> <bytecount> [noreply]\r\n<data block>\r\n

Running and testing

In order to run an automated integration test, just clone this repo and run tox in the root directory (you can install tox using pip install tox). In order to manually test this, follow the instructions.

Prerequisites:

• rust, cargo
• python, pymemcache (pip install pymemcache)

Steps:

1. Ensure that you have rust and cargo installed and execute cargo run. Ensure that the process starts successfully.

2. In a new tab, open a python shell and run the following commands.

from pymemcache.client.base import Client
client = Client(('127.0.0.1', 11212))
client.set('somekey', 'somevalue')
assert b'somevalue' == client.get('somekey')
assert None == client.get('otherkey')

Next steps

• add script to benchmark performance and memory utilization against memcached.
• add more extensive unit and integration testing.
• implement the remaining commands in the memcached protocol.
