Struct PosixCustom

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

A POSIX locale implementation of Custom.

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

Example

This example shows how to use PosixCustom via strtime formatting:

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

let config = Config::new().custom(PosixCustom::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")?,
    "Tue Jul  1 17:30:00 2025",
);
