Struct convergence::connection::Connection

source · [−]

pub struct Connection<E: Engine> { /* private fields */ }

Expand description

Describes a connection using a specific engine. Contains connection state including prepared statements and portals.

Implementations

source

impl<E: Engine> Connection<E>

source

pub fn new(engine: E) -> Self

Create a new connection from an engine instance.

source

pub async fn run(
&mut self,
stream: impl AsyncRead + AsyncWrite + Unpin
) -> Result<(), ConnectionError>

Given a stream (typically TCP), extract Postgres protocol messages and respond accordingly. This function only returns when the connection is closed (either gracefully or due to an error).
