C++ Shorter Fixed Width Types (CSFWT)

This is a single header library that defines shorter versions of the C++ fixed-width types:

Old	New
std::int8_t	i8
std::int16_t	i16
std::int32_t	i32
std::int64_t	i64
std::uint8_t	u8
std::uint16_t	u16
std::uint32_t	u32
std::uint64_t	u64
float	f32
double	f64

These are more similar to Rust's types. This allows you to write code such as:

i32 sum(std::vector<i32> numbers) {
    return std::accumulate(numbers.begin(), numbers.end(), 0);
}

There is also support for f32 and f64 in place of float and double respectively:

f64 mean(std::vector<f64> const numbers) {
    if (numbers.empty()) {
        throw std::invalid_argument("Cannot calculate mean of empty list of numbers.");
    }

    f64 const sum{ std::accumulate(numbers.begin(), numbers.end(), 0.0) };
    f64 const mean{ sum / numbers.size() };

    return mean;
}

The only caveat is that f32 and f64 are minimums, not fixed-width types.

The primary motivation is that these typedefs are more concise and therefore you are more likely to use them.
