Struct taos_query::Manager

pub struct Manager<T> { /* private fields */ }

This is how we manage connections.

Implementations

impl<T: TBuilder> Manager<T>

pub fn new(builder: T) -> Self

pub fn from_dsn<D: IntoDsn>( dsn: D, ) -> RawResult<(Self, BTreeMap<String, String>)>

Build a connection manager from a DSN.

Trait Implementations

impl<T: TBuilder> Default for Manager<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T> DerefMut for Manager<T>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<T: AsyncTBuilder> Manager for Manager<T>

type Type = <T as AsyncTBuilder>::Target

Type of Objects that this Manager creates and recycles.

type Error = Error

Error that this Manager can return when creating and/or recycling Objects.

fn create<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = RawResult<Self::Type>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Creates a new instance of Manager::Type.

fn recycle<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, conn: &'life1 mut Self::Type, _: &'life2 Metrics, ) -> Pin<Box<dyn Future<Output = RecycleResult<Self::Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Tries to recycle an instance of Manager::Type.

fn detach(&self, _obj: &mut Self::Type)

Detaches an instance of Manager::Type from this Manager.

impl<T> Deref for Manager<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
