Struct NumBuffer 

pub struct NumBuffer<T>
where
    T: NumBufferTrait,
{
    pub(crate) buf: <T as NumBufferTrait>::Buf,
    phantom: PhantomData<T>,
}

A buffer wrapper of which the internal size is based on the maximum number of digits the associated integer can have.

Examples

use core::fmt::NumBuffer;

let mut buf = NumBuffer::new();
let n1 = 1972u32;
assert_eq!(n1.format_into(&mut buf), "1972");

// Formatting a negative integer includes the sign.
let mut buf = NumBuffer::new();
let n2 = -1972i32;
assert_eq!(n2.format_into(&mut buf), "-1972");

Fields

buf: <T as NumBufferTrait>::Buf

phantom: PhantomData<T>
