This is a library for formatting numbers with numeric prefixes, such as -//! turning “3000 metres” into “3 kilometres”, or “8705 bytes” into “8.5 KiB”. -//! -//! -//! # Usage -//! -//! The function [`NumberPrefix::decimal`](enum.NumberPrefix.html#method.decimal) -//! returns either a pair of the resulting number and its prefix, or a -//! notice that the number was too small to have any prefix applied to it. For -//! example: -//! -//! ``` -//! use number_prefix::NumberPrefix; -//! -//! let amount = 8542_f32; -//! let result = match NumberPrefix::decimal(amount) { -//! NumberPrefix::Standalone(bytes) => { -//! format!("The file is {} bytes in size", bytes) -//! } -//! NumberPrefix::Prefixed(prefix, n) => { -//! format!("The file is {:.1} {}B in size", n, prefix) -//! } -//! }; -//! -//! assert_eq!("The file is 8.5 kB in size", result); -//! ``` -//! -//! The `{:.1}` part of the formatting string tells it to restrict the -//! output to only one decimal place. This value is calculated by repeatedly -//! dividing the number by 1000 until it becomes less than that, which in this -//! case results in 8.542, which gets rounded down. Because only one division -//! had to take place, the function also returns the decimal prefix `Kilo`, -//! which gets converted to its internationally-recognised symbol when -//! formatted as a string. -//! -//! If the value is too small to have any prefixes applied to it — in this case, -//! if it’s under 1000 — then the standalone value will be returned: -//! -//! ``` -//! use number_prefix::NumberPrefix; -//! -//! let amount = 705_f32; -//! let result = match NumberPrefix::decimal(amount) { -//! NumberPrefix::Standalone(bytes) => { -//! format!("The file is {} bytes in size", bytes) -//! } -//! NumberPrefix::Prefixed(prefix, n) => { -//! format!("The file is {:.1} {}B in size", n, prefix) -//! } -//! }; -//! -//! assert_eq!("The file is 705 bytes in size", result); -//! ``` -//! -//! In this particular example, the user expects different formatting for -//! both bytes and kilobytes: while prefixed values are given more precision, -//! there’s no point using anything other than whole numbers for just byte -//! amounts. This is why the function pays attention to values without any -//! prefixes — they often need to be special-cased. -//! -//! -//! ## Binary Prefixes -//! -//! This library also allows you to use the *binary prefixes*, which use the -//! number 1024 (210) as the multiplier, rather than the more common 1000 -//! (103). This uses the -//! [`NumberPrefix::binary`](enum.NumberPrefix.html#method.binary) function. -//! For example: -//! -//! ``` -//! use number_prefix::NumberPrefix; -//! -//! let amount = 8542_f32; -//! let result = match NumberPrefix::binary(amount) { -//! NumberPrefix::Standalone(bytes) => { -//! format!("The file is {} bytes in size", bytes) -//! } -//! NumberPrefix::Prefixed(prefix, n) => { -//! format!("The file is {:.1} {}B in size", n, prefix) -//! } -//! }; -//! -//! assert_eq!("The file is 8.3 KiB in size", result); -//! ``` -//! -//! A kibibyte is slightly larger than a kilobyte, so the number is smaller -//! in the result; but other than that, it works in exactly the same way, with -//! the binary prefix being converted to a symbol automatically. -//! -//! -//! ## Which type of prefix should I use? -//! -//! There is no correct answer this question! Common practice is to use -//! the binary prefixes for numbers of *bytes*, while still using the decimal -//! prefixes for everything else. Computers work with powers of two, rather than -//! powers of ten, and by using the binary prefixes, you get a more accurate -//! representation of the amount of data. -//! -//! -//! ## Prefix Names -//! -//! If you need to describe your unit in actual words, rather than just with the -//! symbol, use one of the `upper`, `caps`, `lower`, or `symbol`, which output the -//! prefix in a variety of formats. For example: -//! -//! ``` -//! use number_prefix::NumberPrefix; -//! -//! let amount = 8542_f32; -//! let result = match NumberPrefix::decimal(amount) { -//! NumberPrefix::Standalone(bytes) => { -//! format!("The file is {} bytes in size", bytes) -//! } -//! NumberPrefix::Prefixed(prefix, n) => { -//! format!("The file is {:.1} {}bytes in size", n, prefix.lower()) -//! } -//! }; -//! -//! assert_eq!("The file is 8.5 kilobytes in size", result); -//! ``` -//! -//! -//! ## String Parsing -//! -//! There is a `FromStr` implementation for `NumberPrefix` that parses -//! strings containing numbers and trailing prefixes, such as `7.5E`. -//! -//! Currently, the only supported units are `b` and `B` for bytes, and `m` for -//! metres. Whitespace is allowed between the number and the rest of the string. -//! -//! ``` -//! use number_prefix::{NumberPrefix, Prefix}; -//! -//! assert_eq!("7.05E".parse::>(), -//! Ok(NumberPrefix::Prefixed(Prefix::Exa, 7.05_f64))); -//! -//! assert_eq!("7.05".parse::>(), -//! Ok(NumberPrefix::Standalone(7.05_f64))); -//! -//! assert_eq!("7.05 GiB".parse::>(), -//! Ok(NumberPrefix::Prefixed(Prefix::Gibi, 7.05_f64))); -//! ``` - - -#![cfg_attr(not(feature = "std"), no_std)] - -#[cfg(feature = "std")] -mod parse; - -#[cfg(not(feature = "std"))] -use core::ops::{Neg, Div}; - -#[cfg(feature = "std")] -use std::{fmt, ops::{Neg, Div}}; - - -/// A numeric prefix, either binary or decimal. -#[derive(PartialEq, Eq, Clone, Copy, Debug)] -pub enum Prefix { - - /// _kilo_, 103 or 10001. - /// From the Greek ‘χίλιοι’ (‘chilioi’), meaning ‘thousand’. - Kilo, - - /// _mega_, 106 or 10002. - /// From the Ancient Greek ‘μέγας’ (‘megas’), meaning ‘great’. - Mega, - - /// _giga_, 109 or 10003. - /// From the Greek ‘γίγας’ (‘gigas’), meaning ‘giant’. - Giga, - - /// _tera_, 1012 or 10004. - /// From the Greek ‘τέρας’ (‘teras’), meaning ‘monster’. - Tera, - - /// _peta_, 1015 or 10005. - /// From the Greek ‘πέντε’ (‘pente’), meaning ‘five’. - Peta, - - /// _exa_, 1018 or 10006. - /// From the Greek ‘ἕξ’ (‘hex’), meaning ‘six’. - Exa, - - /// _zetta_, 1021 or 10007. - /// From the Latin ‘septem’, meaning ‘seven’. - Zetta, - - /// _yotta_, 1024 or 10008. - /// From the Green ‘οκτώ’ (‘okto’), meaning ‘eight’. - Yotta, - - /// _kibi_, 210 or 10241. - /// The binary version of _kilo_. - Kibi, - - /// _mebi_, 220 or 10242. - /// The binary version of _mega_. - Mebi, - - /// _gibi_, 230 or 10243. - /// The binary version of _giga_. - Gibi, - - /// _tebi_, 240 or 10244. - /// The binary version of _tera_. - Tebi, - - /// _pebi_, 250 or 10245. - /// The binary version of _peta_. - Pebi, - - /// _exbi_, 260 or 10246. - /// The binary version of _exa_. - Exbi, - // you can download exa binaries at https://exa.website/#installation - - /// _zebi_, 270 or 10247. - /// The binary version of _zetta_. - Zebi, - - /// _yobi_, 280 or 10248. - /// The binary version of _yotta_. - Yobi, -} - - -/// The result of trying to apply a prefix to a floating-point value. -#[derive(PartialEq, Eq, Clone, Debug)] -pub enum NumberPrefix { - - /// A **standalone** value is returned when the number is too small to - /// have any prefixes applied to it.
