Struct l337::Conn

pub struct Conn<C> where
    C: ManageConnection,
    C::Connection: Send,  {
    pub conn: Option<Live<C::Connection>>,
    pub pool: Option<Pool<C>>,
    // some fields omitted
}

A smart wrapper around a connection which stores it back in the pool when it is dropped.

This can be dereferences to the Service instance this pool manages, and also implements Service itself by delegating.

Fields

conn: Option<Live<C::Connection>>

Actual connection. This should never become a None variant under normal operation. This is an option so we can take the connection on drop, and push it back into the pool

pool: Option<Pool<C>>

Underlying pool. A reference is stored here so we can push the connection back into the pool on drop. This should never become a None variant under normal operation. This is an option so we can take the connection on drop, and push it back into the pool

Trait Implementations

impl<C> Deref for Conn<C> where
    C: ManageConnection,
    C::Connection: Send, 

type Target = C::Connection

The resulting type after dereferencing.

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

Dereferences the value.

impl<C> DerefMut for Conn<C> where
    C: ManageConnection,
    C::Connection: Send, 

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

Mutably dereferences the value.

impl<C> Drop for Conn<C> where
    C: ManageConnection,
    C::Connection: Send, 

fn drop(&mut self)

Executes the destructor for this type.
