pub enum LevelFilter {
    Off,
    Equal(Level),

Expand description

An enum representing log level logical filter conditions.

A LevelFilter may be compared to a Level through LevelFilter::compare.

Examples

use spdlog::prelude::*;

let level_filter: LevelFilter = LevelFilter::MoreSevere(Level::Info);

assert_eq!(level_filter.compare(Level::Trace), false);
assert_eq!(level_filter.compare(Level::Info), false);
assert_eq!(level_filter.compare(Level::Warn), true);
assert_eq!(level_filter.compare(Level::Error), true);

Variants

`Off`

Disables all levels.

`Equal(Level)`

Enables if the target level is equal to the filter level.

`NotEqual(Level)`

Enables if the target level is not equal to the filter level.

`MoreSevere(Level)`

Enables if the target level is more severe than the filter level.

`MoreSevereEqual(Level)`

Enables if the target level is more severe than or equal to the filter level.

`MoreVerbose(Level)`

Enables if the target level is more verbose than the filter level.

`MoreVerboseEqual(Level)`

Enables if the target level is more verbose than or equal to the filter level.

`All`

Enables all levels.
