How can i write hex decimals to stream ?
i have code like this :
import vibe.d;
import std.stdio;
void run(TCPConnection conn)
{
conn.write(0x00);
conn.write(0x00);
conn.write(0x00);
}
shared static this()
{
listenTCP(3724, (conn) => run(conn));
}
thhis will give me an error, no write's callable with arguments

Hi,
write defined as void write(in ubyte[] bytes);. So you can try conn.write(conn.write(cast(ubyte[])[0x00, 0x00, 0x00]).

Typo.
conn.write(cast(ubyte[])[0x00, 0x00, 0x00]);
To improve performance, and to be able to use D's generic range
functionality, I'd also recommend to wrap the connection into a vibe.stream.wrapper.StreamOutputRange:
auto rng = StreamOutputRange(conn);
rng.put(0x00);
rng.put(0x00);
rng.put(0x00);
This will create a small buffer that will be flushed when full, when rng.flush() is explicitly called, or when it goes out of scope.
