The return type of sequence.
Defined in header <boost/mysql/sequence.hpp>
template< class Range, class FormatFn> struct format_sequence;

Name |
Description |
|---|---|
|
The format function to apply to each element in the range. |
|
|
The string to output between range elements. |
|
|
The range to format. |
Contains a range, a formatter function, and a glue string. This type satisfies
the Formattable concept.
When formatted, format_function is invoked for each
element in range. The string glue is output raw (as per format_context_base::append_raw) between consecutive
invocations of the formatter function, generating an effect similar to std::ranges::views::join.
Don't instantiate this struct directly - use sequence, instead.
std::begin(range)
and std::end(range)
should return an input iterator/sentinel pair that can be compared for
(in)equality.
static_cast<const FormatFn&>(fn)(* std::begin(range), ctx)
should be well formed, with ctx
begin a format_context_base&.
