Enum simplelog::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.

Methods

impl Level

pub fn max() -> Level

Returns the most verbose logging level.

pub fn to_level_filter(&self) -> LevelFilter
