Crate fmtastic 

A fantastic crate for fmting numbers using the appropriate unicode characters via the Display trait. ✨
Supports vulgar fractions, super- and subscript.

Vulgar Fractions

Creates beautiful unicode fractions like ¼ or ¹⁰⁄₃.

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.

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.

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

Tally Marks

Formats an unsigned integer as tally marks.

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.

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)));

Structs

BallotBox

Formats a boolean as either a checked or unchecked ballot box.

Segmented

Formats an unsigned integer using seven-segment digits from the Legacy Computing block.

Subscript

A number that can be formatted as subscript using the Display trait.

Superscript

A number that can be formatted as superscript using the Display trait.

TallyMarks

Formats an unsigned integer as tally marks.

VulgarFraction

A Vulgar Fraction that can be formatted as a unicode fraction using the Display trait.

Traits

Integer

An abstraction over all integer types. Integers can be formatted as Subscript, Subscript or VulgarFraction.

SignedInteger

Abstraction over signed integer types.

UnsignedInteger

Abstraction over unsigned integer types. Unsigned integers can be formatted as Segmented or TallyMarks.
