Formatting User-defined types documentation for 10.0.0 is outdated

[rlalik]

The example shows to use

// Check if reached the end of the range:
    if (it != end && *it != '}') ctx.on_error("invalid format");

but apparently on_error is not a member of the context class. format_error() should be used.

Good catch, thanks. Could you by any chance submit a PR to fix this?

I would still like an answer re. what is the intended way of throwing errors in the formatter parser - other than leaving the iterator as-is while there are unparsed characters. I’d gladly submit a PR but I’m not even sure what it should say :)

As shown in the example the recommended way is to throw format_error.
