Struct kvarn::prelude::networking::prelude::utils::prelude::fmt::FormatterFn
source · pub struct FormatterFn<F>(pub F)
where
F: Fn(&mut Formatter<'_>) -> Result<(), Error>;
🔬This is a nightly-only experimental API. (
debug_closure_helpers
)Expand description
Implements fmt::Debug
and fmt::Display
using a function.
§Examples
#![feature(debug_closure_helpers)]
use std::fmt;
let value = 'a';
assert_eq!(format!("{}", value), "a");
assert_eq!(format!("{:?}", value), "'a'");
let wrapped = fmt::FormatterFn(|f| write!(f, "{:?}", &value));
assert_eq!(format!("{}", wrapped), "'a'");
assert_eq!(format!("{:?}", wrapped), "'a'");
