Struct Connection 

pub struct Connection { /* private fields */ }

Implementations

impl Connection

pub async fn connect(config: &DatabaseConfig) -> Result<Connection>

Open a connection and complete the startup handshake.

pub fn is_broken(&self) -> bool

pub fn in_transaction(&self) -> bool

True while a transaction is open, so the pool never hands back a connection that would leak one.

pub fn is_encrypted(&self) -> bool

Whether this connection is encrypted.

pub async fn simple_query(&mut self, sql: &str) -> Result<QueryResult>

Run a statement with no parameters through the simple query protocol.

Used for DDL and for statements that must run as one unit, such as begin/commit.

pub async fn query( &mut self, sql: &str, params: &[Value], ) -> Result<QueryResult>

Run a parameterised statement through the extended query protocol.

Parameters never enter the SQL text, so a value cannot change the shape of the statement — this is what makes SQL injection structurally impossible rather than a matter of remembering to escape.

pub async fn close(self)

Ask the server to close the session politely.

Trait Implementations

impl DriverConnection for Connection

fn query<'a>( &'a mut self, sql: &'a str, params: &'a [Value], ) -> BoxFuture<'a, Result<QueryResult>>

Run a statement with bound parameters.

fn simple_query<'a>( &'a mut self, sql: &'a str, ) -> BoxFuture<'a, Result<QueryResult>>

Run a statement with no parameters — DDL, and transaction control.

fn is_broken(&self) -> bool

Whether this connection is known to be unusable, so the pool discards it instead of handing it to the next caller.

fn in_transaction(&self) -> bool

Whether a transaction is still open. A connection left inside one must never go back into rotation.

fn close(self: Box<Self>) -> BoxFuture<'static, ()>

Say goodbye politely, then hang up.
