how do i make socket receive specific amount of data

[north atlas]

i have this problem my client is receiving the file name and the file data until that buffer is full i only want it to receive the file name any ideas?

server
send_file_name(filename)
send_data(file data)

client
recv(fille name ) // gets file name and some file data
recv(file data)

I'd presume you're appending it to an array or Vec, so what about slicing it after the fact instead...??

that would be ignoring the problem at best

changing from buf = vec![] to buf = [] fixed it and idk why
