Implementations

impl Level

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

Available on crate feature logging only.

Convert to str from LOG_LEVEL_SHORT_NAMES

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

Available on crate feature logging only.

Convert to str from LOG_LEVEL_NAMES

pub fn as_usize(&self) -> usize

Available on crate feature logging only.

Cast Level to ordering integer

Critical is the smallest and Trace the biggest value

pub fn from_usize(u: usize) -> Option<Level>

Available on crate feature logging only.

Get a Level from an usize

This complements as_usize

impl Level

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

Available on crate feature logging only.

Returns true if self is at least level logging level

Trait Implementations

impl Clone for Level

fn clone(&self) -> Level

Returns a duplicate 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, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<Level> for LogVerbosity

Available on crate feature logging only.

fn from(level: Level) -> Self

Converts to this type from the input type.

impl From<LogVerbosity> for Level

Available on crate feature logging only.

fn from(level: LogVerbosity) -> Self

Converts to this type from the input type.

impl FromStr for Level

type Err = ()

The associated error which can be returned from parsing.

fn from_str(name: &str) -> Result<Level, ()>

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,

Restrict a value to a certain interval.

impl PartialEq for Level

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.

impl PartialOrd for Level

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

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