Enum LevelFilter

#[repr(align(4))]
pub enum LevelFilter {
    Off,
    Equal(Level),
    NotEqual(Level),
    MoreSevere(Level),
    MoreSevereEqual(Level),
    MoreVerbose(Level),
    MoreVerboseEqual(Level),
    All,
}

Represents log level logical filter conditions.

Use LevelFilter::test method to check if a Level satisfies the filter condition.

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.

Implementations

impl LevelFilter

pub fn compare(&self, level: Level) -> bool

👎Deprecated since 0.4.0: it may be removed in the future, use method test() instead

Checks the given level if satisfies the filter condition.

pub fn test(&self, level: Level) -> bool

Checks the given level if satisfies the filter condition.

Examples

use spdlog::prelude::*;

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

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

Trait Implementations

impl Clone for LevelFilter

fn clone(&self) -> LevelFilter

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LevelFilter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<LevelFilter> for LevelFilter

Available on crate feature log only.

fn from(filter: LevelFilter) -> Self

Converts to this type from the input type.

impl Hash for LevelFilter

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for LevelFilter

fn eq(&self, other: &LevelFilter) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
