Enum hugr_cli::Level

#[repr(usize)]
pub enum Level {
    Error = 1,
    Warn = 2,
    Info = 3,
    Debug = 4,
    Trace = 5,
}

We reexport some clap types that are used in the public API. 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 = 1

The “error” level.

Designates very serious errors.

Warn = 2

The “warn” level.

Designates hazardous situations.

Info = 3

The “info” level.

Designates useful information.

Debug = 4

The “debug” level.

Designates lower priority information.

Trace = 5

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

The associated error which can be returned from parsing.

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) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

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

impl PartialEq 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.

impl PartialOrd<LevelFilter> for Level

fn partial_cmp(&self, other: &LevelFilter) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

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

fn le(&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

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