apply
Applies the given log level map to the current context. Log level settings are merged with any existing setting from the current (or parent) contexts such that logging will be enabled for a log statement if:
- It was enabled by the given map.
- It was already enabled by the current context.
The effects of this call will be undone only when the current context terminates.
Return
false if there is no current context, or scoped contexts are not supported.
