Enum DbStream 

pub enum DbStream {
    Plain(TcpStream),
    Tls(Box<TlsStream<TcpStream>>),
    Closed,
}

A socket that may or may not have been upgraded.

An enum rather than a boxed trait object: there are exactly two cases, both known at compile time, and a virtual call per read on a database connection buys nothing. Closed exists for the instant during the handshake when the plain socket has been taken out and the encrypted one is not yet in — a real placeholder, so a bug there reports itself instead of hanging on a dead file descriptor.

Variants

Plain(TcpStream)

Tls(Box<TlsStream<TcpStream>>)

Closed

Implementations

impl DbStream

pub fn is_encrypted(&self) -> bool

pub fn take_plain(&mut self) -> Result<TcpStream>

Take the plain socket out, leaving Closed behind.

Only for the upgrade: a driver calls this, hands the socket to upgrade, and puts the result back.

pub async fn write_all(&mut self, bytes: &[u8]) -> Result<()>

pub async fn flush(&mut self) -> Result<()>

pub async fn read(&mut self, buffer: &mut [u8]) -> Result<usize>

pub async fn shutdown(&mut self) -> Result<()>
