Logging filtering level

Variants

Off

Log nothing

Critical

Log critical level only

Error

Log only error level and above

Log only warning level and above

Info

Methods

impl FilterLevel

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)

Trait Implementations

impl Copy for FilterLevel

impl Clone for FilterLevel

fn clone(&self) -> FilterLevel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FilterLevel

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

Formats the value using the given formatter.

impl Eq for FilterLevel

impl PartialEq for FilterLevel

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

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

impl PartialOrd for FilterLevel

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

type Err = ()

The associated error which can be returned from parsing.

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

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