toAlphaInto

(

size_t maxDigits = 19

uint leadingZeroes = 0

Num

Sink

)

(

const Num num

auto ref Sink sink

)

if (

isIntegral!Num &&

isOutputRange!(Sink, char[])

)

Parameters

maxDigits: The maximum number of digits to expect input of.
leadingZeroes: The minimum amount of leading zeroes to include in the output, mirroring the format specifier "%0nd".
num Num: Integer to translate into string.
sink Sink: Output range sink.

Examples

Appender!(char[]) sink;
int num = 12345;
num.toAlphaInto(sink);
assert(sink.data == "12345");
assert(sink.data == num.to!string);
