How to create string from uint8[] in Vala?

I am doing async reads from a DataInputStream filling a buffer with bytes.

uint8[] buffer = new uint8[4096];
size_t bytes = 0;
bool success = false;

do
{
  success = yield process.get_stdout_pipe().read_all_async(
    buffer,
    GLib.Priority.LOW, 
    null, 
    out bytes
  );
{
while(success && bytes > 0);

I want to combine the data into a string. I had a look at StringBuilder but that has no function to append any arrays.

What is the best approach to build a string while async reading?

Solution

  • You can just cast uint8[] to string anytime.
    Code:

    uint8[] chars = {31,32,33,34,35,36,37};
print(@"$((string) chars)\n");

    Output:

    !"#$%
