Struct fn_formats::DisplayFmt

pub struct DisplayFmt<Fmt>(pub Fmt)
 where
    Fmt: Fn(&mut Formatter<'_>) -> Result;

Implements Display by calling the stored closure.

Example

use fn_formats::DisplayFmt;

let display = DisplayFmt(|f| write!(f, "display"));

assert_eq!(format!("{}", display), "display");
