Enum uniffi::deps::log::Level

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

An enum representing the available verbosity levels of the logger.

Typical usage includes: checking if a certain Level is enabled with log_enabled!, specifying the Level of log!, and comparing a Level directly to a LevelFilter.

Variants

Error

The “error” level.

Designates very serious errors.

Warn

The “warn” level.

Designates hazardous situations.

Info

The “info” level.

Designates useful information.

Debug

The “debug” level.

Designates lower priority information.

Trace

The “trace” level.

Designates very low priority, often extremely verbose, information.

Implementations

impl Level

pub fn max() -> Level

Returns the most verbose logging level.

pub fn to_level_filter(&self) -> LevelFilter

Converts the Level to the equivalent LevelFilter.

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

Returns the string representation of the Level.

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

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

Iterate through all supported logging levels.

The order of iteration is from more severe to less severe log messages.

Examples

use log::Level;

let mut levels = Level::iter();

assert_eq!(Some(Level::Error), levels.next());
assert_eq!(Some(Level::Trace), levels.last());

Trait Implementations

impl Clone for Level

fn clone(&self) -> Level

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Level

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

Formats the value using the given formatter.

impl Display for Level

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

Formats the value using the given formatter.

impl FromStr for Level

type Err = ParseLevelError

fn from_str(level: &str) -> Result<Level, <Level as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for Level

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 Level

fn cmp(&self, other: &Level) -> 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 Level

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.

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.

impl PartialEq<LevelFilter> for Level

fn eq(&self, other: &LevelFilter) -> 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 less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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