ConnID is used to identify a connection in a connection pool. These IDs are not unique and multiple connections can have the same ID. IDs are used to filter which connections can be used for a specific Request in a way that is independent of what a Request is.

Provided Methods

fn attributes(&self) -> impl Iterator<Item = KeyValue>

Returns a list of attributes to add to metrics generated by the connection pool.

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.
