PoolExt in cap_net_ext - Rust

pub trait PoolExt: Sealed {

}

A trait for extending Pool types.

These functions have a ToSocketAddrs argument, which can return either IPv4 or IPv6 addresses, however they also require the socket to be created with a specific address family up front. Consequently, it’s recommended to do address resolution outside of this API and just pass resolved SocketAddrs in.

This trait is not dyn compatible.

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