Methods

impl Level

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

Convert to str from LOG_LEVEL_SHORT_NAMES

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

Convert to str from LOG_LEVEL_NAMES

fn as_usize(&self) -> usize

Cast Level to ordering integer

Critical is the smallest and Trace the biggest value

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

Get a Level from an usize

This complements as_usize

impl Level

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

Returns true if self is at least level logging level

Trait Implementations

impl Copy for Level

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, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Eq for Level

impl PartialEq for Level

fn eq(&self, __arg_0: &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 !=.

impl Ord for Level

fn cmp(&self, __arg_0: &Level) -> Ordering

This method returns an Ordering between self and other.

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

🔬 This is a nightly-only experimental API. (ord_max_min)

Compares and returns the maximum of two values.

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

🔬 This is a nightly-only experimental API. (ord_max_min)

Compares and returns the minimum of two values.

impl PartialOrd for Level

fn partial_cmp(&self, __arg_0: &Level) -> 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.

impl FromStr for Level

type Err = ()

The associated error which can be returned from parsing.

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

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

impl Display for Level

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
