Trait Manager 

pub trait Manager: Sync + Send {
    type Type: Send;
    type Error: Send;

    // Required methods
    fn create(
        &self,
    ) -> impl Future<Output = Result<Self::Type, Self::Error>> + Send;
    fn recycle(
        &self,
        obj: &mut Self::Type,
        metrics: &Metrics,
    ) -> impl Future<Output = RecycleResult<Self::Error>> + Send;

    // Provided method
    fn detach(&self, _obj: &mut Self::Type) { ... }
}

Manager responsible for creating new super::Objects or recycling existing ones.

Required Associated Types

type Type: Send

Type of super::Objects that this Manager creates and recycles.

type Error: Send

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

Required Methods

fn create(&self) -> impl Future<Output = Result<Self::Type, Self::Error>> + Send

Creates a new instance of Manager::Type.

fn recycle( &self, obj: &mut Self::Type, metrics: &Metrics, ) -> impl Future<Output = RecycleResult<Self::Error>> + Send

Tries to recycle an instance of Manager::Type.

Errors

Returns Manager::Error if the instance couldn’t be recycled.

Provided Methods

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

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

This method is called when using the super::Object::take() method for removing an super::Object from a super::Pool. If the Manager doesn’t hold any references to the handed out super::Objects then the default implementation can be used which does nothing.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
