Function std.base64.Base64Impl.encodeLength

Calculates the length needed to store the encoded string corresponding to an input of the given length.

size_t encodeLength (
  in size_t sourceLength
) pure nothrow @nogc @safe;


sourceLength Length of the source array.


The length of a Base64 encoding of an array of the given length.


ubyte[] data = [0x1a, 0x2b, 0x3c, 0x4d, 0x5d, 0x6e];

// Allocate a buffer large enough to hold the encoded string.
auto buf = new char[Base64.encodeLength(data.length)];

Base64.encode(data, buf);
writeln(buf); // "Gis8TV1u"
