An adapter for using std::io::Write implementations with fmt::Write.

This is useful when one wants to format a datetime or span directly to something with a std::io::Write trait implementation but not a fmt::Write implementation.

Example

use std::{fs::File, io::{BufWriter, Write}, path::Path};

use jiff::{civil::date, fmt::{StdIoWrite, temporal::DateTimePrinter}};

let zdt = date(2024, 6, 15).at(7, 0, 0, 0).in_tz("America/New_York")?;

let path = Path::new("/tmp/output");
let mut file = BufWriter::new(File::create(path)?);
DateTimePrinter::new().print_zoned(&zdt, StdIoWrite(&mut file)).unwrap();
file.flush()?;
assert_eq!(
    std::fs::read_to_string(path)?,
    "2024-06-15T07:00:00-04:00[America/New_York]",
);
