Struct kumo_server_common::config_handle::ConfigHandle
source · pub struct ConfigHandle<T: Clone + Send> { /* private fields */ }
Expand description
ConfigHandle allows sharing a configuration value of some type T without requiring full Mutex around every read operation.
The update method update the upstream value, bumping the generation counter in the process.
The borrow method will return a Guard referencing the value without requiring a Mutex lock operation.
