# fmtastic ✨

[![Docs](https://img.shields.io/docsrs/fmtastic/latest)](https://docs.rs/fmtastic)
[![Crate Version](https://img.shields.io/crates/v/fmtastic)](https://crates.io/crates/fmtastic)

A **fantastic**, `#![no_std]`-friendly crate for **fmt**ing numbers using the appropriate unicode characters via the [`Display`] trait. ✨
Format as vulgar fractions, super- and subscript and more.

Contributions are welcome for more formats.

## Features

### [Vulgar Fractions]
Creates beautiful unicode fractions like ¼ or ¹⁰⁄₃.
```rust
use fmtastic::VulgarFraction;

assert_eq!("¹⁰⁄₃", format!("{}", VulgarFraction::new(10, 3)));
assert_eq!("¼", format!("{}", VulgarFraction::new(1, 4)));
```

### Sub- and superscript
Formats integers as sub- or superscript. 

```rust
use fmtastic::{Subscript, Superscript};

assert_eq!("x₁", format!("x{}", Subscript(1)));
assert_eq!("n²", format!("n{}", Superscript(2)));
```

### Seven-Segment Digits
Formats an unsigned integer using seven-segment digits
from the [Legacy Computing] block.

```rust
use fmtastic::Segmented;

assert_eq!("🯶🯲🯸", format!("{}", Segmented(628_u32)));
```

### Tally Marks
Formats an unsigned integer as tally marks.
```rust
use fmtastic::TallyMarks;

assert_eq!("𝍷𝍷𝍷", TallyMarks(3_u32).to_string());
assert_eq!("𝍸𝍸𝍷𝍷", TallyMarks(12_u32).to_string());
```

### Ballot Box
Formats a boolean as a ballot box.

```rust
use fmtastic::BallotBox;

assert_eq!("☑ Buy bread", format!("{} Buy bread", BallotBox(true)));
assert_eq!("☐ Do the dishes", format!("{} Do the dishes", BallotBox(false)));
assert_eq!("☒ Laundry", format!("{:#} Laundry", BallotBox(true)));
```
