pub enum LevelFilter {
    Off,
    Error,
    Warn,
    Info,
    Debug,
    Trace,
}

[−] Expand description

An enum representing the available verbosity level filters of the logger.

A LevelFilter may be compared directly to a Level. Use this type to get and set the maximum log level with max_level() and set_max_level.

Variants

Off

[−] Expand description

A level lower than all log levels.

Error

[−] Expand description

Corresponds to the Error log level.

Warn

[−] Expand description

Corresponds to the Warn log level.

Info

[−] Expand description

Corresponds to the Info log level.

Debug

[−] Expand description

Corresponds to the Debug log level.

Trace

[−] Expand description

Corresponds to the Trace log level.
