Enum log::Level [] [src]

#[repr(usize)]
pub enum Level { Error, Warn, Info, Debug, Trace, }

An enum representing the available verbosity levels of the logger.

Typical usage includes: checking if a certain Level is enabled with log_enabled!, specifying the Level of log!, and comparing a Level directly to a LevelFilter.

Variants

The "error" level.

Designates very serious errors.

The "warn" level.

Designates hazardous situations.

The "info" level.

Designates useful information.

The "debug" level.

Designates lower priority information.

The "trace" level.

Designates very low priority, often extremely verbose, information.
