Prust

Prust is a simple example of a pastebin service.

It stores its data in a postgresql database.

It doesn't come with a lot of bells and whistles but does work as a very basic pastebin service written in Rust.

It is mostly meant as a learning project, and to poke at the various web frameworks available.

Running

In order to run prust you'll need a running postgres database with an initialized schema before you can start the exectable (or simply cargo run).

The provided docker-compose.yaml should allow you to get a non-persistent test database to run prust against in seconds:

docker-compose up

In another terminal, you should now be able to load the initial schema into the running docker container with:

cat schema/prust.sql | docker exec -i prust_database_1 psql -U prust

Running cargo run on the top-level directory should start prust on a reasonable Rust version (this was developped on stable on Ubuntu 20.10)

The server is started on port 3000, to which you can point a web browser.

For now the basic functionality is there but there's a few things missing:

Proper HTML
Add some validation to the input (a paste should have a maximum size, so should the author field)
Add some HTML escalping to the rendering back (right now it's vulnerable to code injection)
Add a LRU-like invalidation to pastes (keeping e.g. 500 in memory).
Add an upper memory limit for the LRU cache instead of number of entries.
Add a Dockerfile
Add a Helm chart to make k8s deployments trivial
