Struct DefaultCustom 

pub struct DefaultCustom(/* private fields */);

The default trait implementation of Custom.

Whenever one uses the formatting or parsing routines in this module without providing a configuration, then this customization is the one that gets used.

The behavior of the locale formatting of this type is meant to match that of Unicode’s und locale.

Example

This example shows how to explicitly use DefaultCustom via strtime formatting:

use jiff::{civil, fmt::strtime::{BrokenDownTime, DefaultCustom, Config}};

let config = Config::new().custom(DefaultCustom::new());
let dt = civil::date(2025, 7, 1).at(17, 30, 0, 0);
let tm = BrokenDownTime::from(dt);
assert_eq!(
    tm.to_string_with_config(&config, "%c")?,
    "2025 M07 1, Tue 17:30:00",
);
