[−] Expand description

An enum representing the available verbosity levels of the logging framework

A LogLevel may be compared directly to a LogLevelFilter.

Variants

Error

[−] Expand description

The "error" level.

Designates very serious errors.

Warn

[−] Expand description

The "warn" level.

Designates hazardous situations.

Info

[−] Expand description

The "info" level.

Designates useful information.

Debug

[−] Expand description

The "debug" level.

Designates lower priority information.

Trace

[−] Expand description

The "trace" level.

Designates very low priority, often extremely verbose, information.
