# [−] [src] Enum log::Level

    #[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

`Error`

The "error" level.

Designates very serious errors.

`Warn`

The "warn" level.

Designates hazardous situations.

`Info`

The "info" level.

Designates useful information.

`Debug`

The "debug" level.

Designates lower priority information.

`Trace`

The "trace" level.

Designates very low priority, often extremely verbose, information.
