Struct LevelConfig

pub struct LevelConfig { /* private fields */ }

LevelConfig stores the relation target->LevelFilter in a hash table.

The table supports copying from the logger system LevelConfig to a widget’s LevelConfig. In order to detect changes, the generation of the hash table is compared with any previous copied table. On every change the generation is incremented.
