Function calcSize [src]

Compute the encoded length

Prototype

pub fn calcSize(encoder: *const Base64Encoder, source_len: usize) usize

Parameters

encoder: *const Base64Encodersource_len: usize

Source

  pub fn calcSize(encoder: *const Base64Encoder, source_len: usize) usize {
    if (encoder.pad_char != null) {
        return @divTrunc(source_len + 2, 3) * 4;
    } else {
        const leftover = source_len % 3;
        return @divTrunc(source_len, 3) * 4 + @divTrunc(leftover * 4 + 2, 3);
    }
}
