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

A level lower than all log levels.

Error

Corresponds to the Error log level.

Warn

Corresponds to the Warn log level.

Info

Corresponds to the Info log level.

Debug

Corresponds to the Debug log level.

Trace

Corresponds to the Trace log level.

Implementations

Returns the most verbose logging level filter.

Converts self to the equivalent Level.

Returns None if self is LevelFilter::Off.

Returns the string representation of the LevelFilter.

This returns the same string as the fmt::Display implementation.

Iterate through all supported filtering levels.

The order of iteration is from less to more verbose filtering.

Examples
use log::LevelFilter;

let mut levels = LevelFilter::iter();

assert_eq!(Some(LevelFilter::Off), levels.next());
assert_eq!(Some(LevelFilter::Trace), levels.last());
