A simple Discord Markov Chain bot written in Rust

Simple Rust Markov Chain Bot

Should be fairly straightforward to run. Simply:

DISCORD_TOKEN=your_bot_token_here cargo run --release

Doesn't have any shared library dependencies or anything.

Design

By design, it reads every message and filters out staff-only channels (determined by channel name), then splits the message contents into words, and creates key-value pairs of (word, list_of_words_that_may_follow). If the list of following words is greater than 64 entries, the first one is popped before adding a new one. The "weight" of each word is determined by how many times it shows up in the list.

It's triggered on every message that contains Luna (case-insensitive), followed by any of the following keywords: what tell say thought opinion

Example:

Luna, what do you think?
Luna say something
I think Luna should tell us something

Todos

Maybe I'll make it more sane or something. I dunno. This was a simple Rust exercise designed to be tested in production. Don't test in production though.
