marustdown 0.1.4

# marustdown

A fast terminal markdown viewer with **syntax highlighting**, task lists you can check
off, and an outline for jumping around. See the [README](../README.md) for more.

## Code

```rust
use std::collections::HashMap;

/// Counts how often each word appears.
fn word_count(text: &str) -> HashMap<&str, usize> {
    let mut counts = HashMap::new();
    for word in text.split_whitespace() {
        *counts.entry(word).or_insert(0) += 1; // one more
    }
    counts
}
```

## Math

LaTeX becomes Unicode: Euler's identity $e^{i\pi} + 1 = 0$, a sum
$\sum_{i=1}^{n} i = \frac{n(n+1)}{2}$, or sets like $x \in \mathbb{R}$.

$$
\int_0^\infty e^{-x^2}\,dx = \frac{\sqrt{\pi}}{2}
$$

$$
A = \begin{pmatrix} a & b \\ c & d \end{pmatrix}
$$
