Trait PoolableConnection

pub trait PoolableConnection:
    Unpin
    + Send
    + Sized
    + 'static {
    // Required methods
    fn is_open(&self) -> bool;
    fn can_share(&self) -> bool;
    fn reuse(&mut self) -> Option<Self>;
}

Available on crate feature client only.

A crate::client::conn::Connection that can be pooled.

These connections must report to the pool whether they remain open, and whether they can be shared / multiplexed.

The pool will call PoolableConnection::reuse to get a new connection to return to the pool, which will multiplex against this one. If multiplexing is not possible, then None should be returned.

Required Methods

fn is_open(&self) -> bool

Returns true if the connection is open.

fn can_share(&self) -> bool

Returns true if the connection can be shared / multiplexed.

If this returns true, then PoolableConnection::reuse will be called to get a new connection to return to the pool.

fn reuse(&mut self) -> Option<Self>

Returns a new connection to return to the pool, which will multiplex against this one if possible.

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.
