Trait numtoa::NumToA [−] [src]

pub trait NumToA<T> {
    fn numtoa(self, base: T, string: &mut [u8]) -> usize;
}

Converts a number into a string representation, storing the conversion into a mutable byte slice.

Required Methods

Given a base for encoding and a mutable byte slice, write the number into the byte slice and return the indice where the inner string begins. The inner string can be extracted by slicing the byte slice from that indice.

Panics

If the supplied buffer is smaller than the number of bytes needed to write the integer, this will panic.

Example

use numtoa::NumToA;
use std::io::{self, Write};

let stdout = io::stdout();
let stdout = &mut io::stdout();

let mut buffer = [0u8; 20];
let number = 15325;
let start_indice = number.numtoa(10, &mut buffer);
let _ = stdout.write(&buffer[start_indice..]);
assert_eq!(&buffer[start_indice..], b"15325");
