Struct sqlx::pool::PoolConnection

pub struct PoolConnection<C> where
    C: Connection + Connect<Connection = C>,  { /* fields omitted */ }

A connection checked out from Pool.

Will be returned to the pool on-drop.

Trait Implementations

impl<C> Connection for PoolConnection<C> where
    C: Connection + Connect<Connection = C>, 

fn close(
    self
) -> Pin<Box<dyn Future<Output = Result<(), Error>> + 'static + Send>>

Detach the connection from the pool and close it nicely.

fn ping(&mut self) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send>>

Verifies a connection to the database is still alive.

impl<C> Deref for PoolConnection<C> where
    C: Connection + Connect<Connection = C>, 

type Target = C

The resulting type after dereferencing.

fn deref(&self) -> &<PoolConnection<C> as Deref>::Target

Dereferences the value.

impl<C> DerefMut for PoolConnection<C> where
    C: Connection + Connect<Connection = C>, 

fn deref_mut(&mut self) -> &mut <PoolConnection<C> as Deref>::Target

Mutably dereferences the value.

impl<C> Drop for PoolConnection<C> where
    C: Connection + Connect<Connection = C>, 

Returns the connection to the Pool it was checked-out from.

fn drop(&mut self)

Executes the destructor for this type.

impl<C> Executor for PoolConnection<C> where
    C: Connection + Connect<Connection = C>, 

type Database = <C as Executor>::Database

fn send<'e, 'q>(
    &'e mut self,
    commands: &'q str
) -> Pin<Box<dyn Future<Output = Result<(), Error>> + 'e + Send>> where
    'q: 'e, 

Send a raw SQL command to the database.

fn execute<'e, 'q>(
    &'e mut self,
    query: &'q str,
    args: <<C as Executor>::Database as Database>::Arguments
) -> Pin<Box<dyn Future<Output = Result<u64, Error>> + 'e + Send>> where
    'q: 'e, 

Execute the query, returning the number of rows affected.

fn fetch<'e, 'q>(
    &'e mut self,
    query: &'q str,
    args: <<C as Executor>::Database as Database>::Arguments
) -> Pin<Box<dyn Stream<Item = Result<<<C as Executor>::Database as Database>::Row, Error>> + 'e + Send>> where
    'q: 'e, 

Executes the query and returns a [Stream] of [Row].

fn fetch_optional<'e, 'q>(
    &'e mut self,
    query: &'q str,
    args: <<C as Executor>::Database as Database>::Arguments
) -> Pin<Box<dyn Future<Output = Result<Option<<<C as Executor>::Database as Database>::Row>, Error>> + 'e + Send>> where
    'q: 'e, 

Executes the query and returns up to resulting record.

fn describe<'e, 'q>(
    &'e mut self,
    query: &'q str
) -> Pin<Box<dyn Future<Output = Result<Describe<<PoolConnection<C> as Executor>::Database>, Error>> + 'e + Send>> where
    'q: 'e, 

fn fetch_one<'e, 'q>(
    &'e mut self,
    query: &'q str,
    args: <Self::Database as Database>::Arguments
) -> Pin<Box<dyn Future<Output = Result<<Self::Database as Database>::Row, Error>> + 'e + Send>> where
    'q: 'e, 

Execute the query and return at most one resulting record.
