Implementations

impl FilterLevel

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

Convert to str from LOG_LEVEL_SHORT_NAMES

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

Convert to str from LOG_LEVEL_NAMES

pub fn as_usize(&self) -> usize

Convert to usize value

Off is 0, and Trace 6

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

Get a FilterLevel from an usize

This complements as_usize

pub fn max() -> Self

Maximum logging level (log everything)

pub fn min() -> Self

Minimum logging level (log nothing)

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

Check if message with given level should be logged

Trait Implementations

impl Clone for FilterLevel

fn clone(&self) -> FilterLevel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for FilterLevel

impl Debug for FilterLevel

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

Formats the value using the given formatter.

impl Display for FilterLevel

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

impl Eq for FilterLevel

impl FromStr for FilterLevel

type Err = ()

The associated error which can be returned from parsing.

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

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

impl Ord for FilterLevel

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

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<FilterLevel> for FilterLevel

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

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

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<FilterLevel> for FilterLevel

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

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

#[must_use]pub fn lt(&self, other: &Rhs) -> bool

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

#[must_use]pub fn le(&self, other: &Rhs) -> bool

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

#[must_use]pub fn gt(&self, other: &Rhs) -> bool

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

#[must_use]pub fn ge(&self, other: &Rhs) -> bool

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