# Description of Changes
This changes the behavior on the rust client, so that we let the server
generate the connection id if the client hasn't called the unstable
method to set a connection id.
This is awkward for the `connection_id` function, since it now panics if
the connection id hasn't been received from the server. We should
deprecate this function in favor of a `try` version.
This also changes the behavior of reusing the connection id if a client
reconnects.
The corresponding private PR is
https://github.com/clockworklabs/SpacetimeDBPrivate/pull/1921.
# API and ABI breaking changes
Technically not changing any API signatures, but this is
behavior-changing, since the `connection_id` function can now panic.
# Expected complexity level and risk
2. The risk here is people relying on that behavior.
# Testing
I think some tests need to be updated.
Noa
