Detailed Description

Format only the elements of a range that satisfy a predicate.

Use microfmt::filter with an iterable range or a raw pointer and count. The view stores the predicate without allocation and evaluates it as output is formatted. Use b, c, or n to select square brackets, braces, or no outer delimiters; the remaining specifier is forwarded to each matching element.
