markdown style test

This is a placeholder post. It shows each Markdown element, so we can check the styles. Text can be bold, italic, or inline code, and it can have a link.

A level 2 heading

Each section starts with a level 2 heading. The post title is the only level 1 heading.

A level 3 heading

• A list item.
• A second list item, with more text so that it wraps onto a second line on narrow screens.
  • A nested item.
• A third list item.

1. The first step.
2. The second step.
3. The third step.

A quote has a rule on its left side. It can have more than one line.

Code

use std::collections::BTreeMap;

/// An order book side, keyed by price in ticks.
pub struct Side {
    levels: BTreeMap<u64, u64>,
}

impl Side {
    pub fn add(&mut self, price: u64, amount: u64) {
        *self.levels.entry(price).or_insert(0) += amount; // Merge into the level.
    }
}

A code block without a language has no label:

$ pandoc lua build.lua
build: wrote 4 post(s)
