Enum workflow_log::LevelFilter

#[repr(usize)]
pub enum LevelFilter {
    Off,
    Error,
    Warn,
    Info,
    Debug,
    Trace,
}

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

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 log::LevelFilter;

let mut levels = LevelFilter::iter();

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

Trait Implementations

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

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 Hash for LevelFilter

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

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 Ord for LevelFilter

fn cmp(&self, other: &LevelFilter) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

impl PartialEq<Level> for LevelFilter

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

This method tests for self and other values to be equal, and is used by ==.

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

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