wording
- I'd like to write a TCP client in Rust that can receive the entire message sent by a server, but I have no information about the length of a message.
- I'm aware that TCP [doesn't preserve message boundaries](https://stackoverflow.com/questions/9563563/what-is-a-message-boundary#9563694).
- **Still, what's the best I can do to read the entire message from the [`TcpStream`](https://doc.rust-lang.org/std/net/struct.TcpStream.html)?**
- In the scenario the client should work, there's no protocol for the messages sent from server to client: The client doesn't know beforehand how many bytes are in a message and the message doesn't have a header (as in HTTP) that would contain the message length. There's no special delimiter that marks the end of a message.
- Also, the server might keep the TCP connection open after sending a message, meaning I can not rely on every message being completed with a server [FIN](https://en.wikipedia.org/wiki/Transmission_Control_Protocol#Connection_termination).
I'd like to do this preferably using Rust's standard library only, no other dependencies.

Read all data from TCP stream
I'd like to write a TCP client in Rust that can receive the entire message sent by a server, but I have no information about the length of a message. I'm aware that TCP [doesn't preserve message boundaries](https://stackoverflow.com/questions/9563563/what-is-a-message-boundary#9563694). **Still, what's the best I can do to read the entire message from the [`TcpStream`](https://doc.rust-lang.org/std/net/struct.TcpStream.html)?** In the scenario the client should work, there's no protocol for the messages sent from server to client: The client doesn't know beforehand how many bytes are in a message and the message doesn't have a header (as in HTTP) that would contain the message length.
