Crate fn_formats 

This is a small shim library for passing closures where you need a format trait.

Example

use fn_formats::DebugFmt;

let formattable = DebugFmt(|f| {
    f.debug_struct("StructName")
        .field("list", &DebugFmt(|f| f.debug_list().entries(&[1, 2, 3]).finish()))
        .field("set", &DebugFmt(|f| f.debug_set().entries(&[4, 5, 6]).finish()))
        .finish()
});

assert_eq!(format!("{:?}", formattable), "StructName { list: [1, 2, 3], set: {4, 5, 6} }");

There are also From implementations where applicable:

use fn_formats::ComprehensiveFmt;
let _: ComprehensiveFmt<_> = (|f: &mut core::fmt::Formatter| Ok(())).into();
