Struct mz_server_core::ConnectionUuidHandle

source ·
pub struct ConnectionUuidHandle(pub(crate) Arc<Mutex<Option<Uuid>>>);
Expand description

A handle that permits getting and setting the UUID for a Connection.

A connection’s UUID is a globally unique value that can identify a given connection across environments and process boundaries. Connection UUIDs are never reused.

This is distinct from environmentd’s concept of a “connection ID”, which is a u32 that only identifies a connection within a given environment and only during its lifetime. These connection IDs are frequently reused.
