Enum LevelFilter 

#[repr(u32)]
pub enum LevelFilter {
    Off = 0,
    Fatal = 1,
    Error = 2,
    Warn = 3,
    Info = 4,
    Debug = 5,
    Trace = 6,
}

An enum representing the available verbosity level filters of the logger.

Variants

Off = 0

A level lower than all log levels.

Fatal = 1

Corresponds to the Fatal log level.

Error = 2

Corresponds to the Error log level.

Warn = 3

Corresponds to the Warn log level.

Info = 4

Corresponds to the Info log level.

Debug = 5

Corresponds to the Debug log level.

Trace = 6

Corresponds to the Trace log level.

Implementations

impl LevelFilter

pub fn max() -> LevelFilter

Returns the most verbose logging level filter.

pub fn to_level(self) -> Option<Level>

Converts self to the equivalent Level.

Returns None if self is LevelFilter::Off.

pub fn as_str(self) -> &'static str

Returns the string representation of the LevelFilter.

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

pub fn iter() -> impl Iterator<Item = LevelFilter>

Iterate through all supported filtering levels.

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

Examples

use micromegas_tracing::prelude::*;

let mut levels = LevelFilter::iter();

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

Trait Implementations

Performs copy-assignment from source.

impl Debug for LevelFilter

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

Formats the value using the given formatter.

impl Display for LevelFilter

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

impl PartialEq<Level> for LevelFilter

fn eq(&self, other: &Level) -> 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.
