pub const ERROR: LevelFilter

The "error" level.

Designates very serious errors.

pub const WARN: LevelFilter

The "warn" level.

Designates hazardous situations.

pub const INFO: LevelFilter

The "info" level.

Designates useful information.

pub const DEBUG: LevelFilter

The "debug" level.

Designates lower priority information.

pub const TRACE: LevelFilter
