Here’s a Rust Riddlelist that bids the world hello:

fn main() {
    println!("Hello, World!");
}

Let us walk through the words of this riddlelist step by step and come to ken how it drives the reckoner to weave a greeting.

Do not — as some ungracious pastors do —

Show me the steep and thorny way to heaven,

Whilst, like a puffed and reckless libertine,

Himself the primrose path of dalliance treads,

And recks not his own rede.

  - Ophelia to Laertes, Hamlet, Act I Scene 3

(Inspired by Poul Anderson’s Uncleftish Beholding)

Wordcraft

    fn main():

This is the inway of the Rust riddlelist. Runwork starts here.

The rune fn marks a workflow, and main is the name of this workflow.

fn is from the Frankish for workflow, function.

    { ... }

The curlwrappers hold the wordcraft that makes up the body of the main workflow.

    println!("Hello, World!");

This row of our list shows the words "Hello World!" on the showglass.

It calls upon the println! inwoven-word, which is built into the Rust Groundbookhold. The name is self-kenning, to those who speak a bit of Frankish: it prints a line. We might name it showrow in our tongue.

We call upon println! – or any inwoven-word or workflow – with roundwrappers. A call shifts the steer of our riddlelist, handing the tiller to the called workflow.

How It Unfolds

Builder

First, the Rust builder, rustc, weaves a riddlelist in the reckoner’s tongue out of our fount wordcraft.

Reck that the c in rustc is from the Frankish for builder, compiler.

As it weaves, so also does the builder scrutinize our riddlelist. The forge marks kindrightness, wordhold-welfare (Rust is a tongue that cares much for wordhold-welfare, domain of the borrow-marker), and so forth.

These do not worry us now, for our riddlelist is so groundish. But the Rust builder is a mighty friend when riddlelists become more fiendish, and so a Rust riddlelister learns to reck its rede well and to heed its warnings.

The builder also reworks our inwoven-word, println!, into a workflow like our main – but we do not ever see this middle wordcraft.

rustc makes a runnable twoname, which we can then run on our reckoner.

Runwork

When we run the twoname the reckoner’s runwarden, helmsman of the hardware, shifts steer to the inway – our main workflow.

And "Hello World!" is shewn on the showglass!

Hello World!

Ending

Our riddlelist is now done, and steer goes back to the runwarden.

For such a groundish riddlelist, all of these works – inwoven-words, fount wordcraft and reckoner’s tongue, runwardens – might strike as overkill.

But as you learn to weave your own riddlelists with wendings most wonderful, the might of these works will be made open to sight.

Good luck!
