Struct coord::ConnClient

pub struct ConnClient {
    conn_id: u32,
    inner: Client,
}

A coordinator client that is bound to a connection.

The ConnClient automatically allocates an ID for the connection when it is created, and frees that ID for potential reuse when it is dropped.

See also Client.

Fields

conn_id: u32

inner: Client

Implementations

impl ConnClient

pub fn conn_id(&self) -> u32

Returns the ID of the connection associated with this client.

pub async fn startup(
    self,
    session: Session
) -> Result<(SessionClient, StartupResponse), CoordError>

Upgrades this connection client to a session client.

A session is a connection that has successfully negotiated parameters, like the user. Most coordinator operations are available only after upgrading a connection to a session.

Returns a new client that is bound to the session and a response containing various details about the startup.

pub async fn cancel_request(&mut self, conn_id: u32, secret_key: u32)

Cancels the query currently running on another connection.

async fn send<T, F>(&mut self, f: F) -> T where
    F: FnOnce(Sender<T>) -> Command,
