Detailed Description

Format map-like ranges with zero-allocation key and value views.

Use microfmt::map_view with standard map containers, iterator ranges, or custom key/value extractors for intrusive and flat containers. Default formatting renders {key: value} entries. Use b, c, or n to select brackets, braces, or no outer delimiters; remaining format characters are forwarded to both keys and values.
