Just testing how CI works with this. I tend to prefer vendoring, as it
means that if you have a copy of the code *you can always build it*.
Even if you're 20 years in the future

This is the output of

```

+
+//! 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 (2<sup>10</sup>) as the multiplier, rather than the more common 1000
+//! (10<sup>3</sup>). 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::<NumberPrefix<_>>(),
+//!            Ok(NumberPrefix::Prefixed(Prefix::Exa, 7.05_f64)));
+//!
+//! assert_eq!("7.05".parse::<NumberPrefix<_>>(),
+//!            Ok(NumberPrefix::Standalone(7.05_f64)));
+//!
+//! assert_eq!("7.05 GiB".parse::<NumberPrefix<_>>(),
+//!            Ok(NumberPrefix::Prefixed(Prefix::Gibi, 7.05_f64)));
+//! ```
