Function std.format.sformat

Format arguments into buffer buf which must be large enough to hold the result.

char[] sformat(alias fmt, Args...) (
  char[] buf,
  Args args
)
if (isSomeString!(typeof(fmt)));

char[] sformat(Char, Args...) (
  scope return char[] buf,
  scope const(Char)[] fmt,
  Args args
);

Returns

The slice of buf containing the formatted string.

Throws

A RangeError if buf isn't large enough to hold the formatted string.

A FormatException if the length of args is different than the number of format specifiers in fmt.

Example

The format string can be checked at compile-time (see format for details):

char[10] buf;

writeln(buf[].sformat!"foo%s"('C')); // "fooC"
writeln(sformat(buf[], "%s foo", "bar")); // "bar foo"
