    Warn,
    Error,
}

Log levels

Ordered from most verbose to least: Trace < Debug < Info < Warn < Error

Variants

Info

Informational messages (default)

Warn

Warning messages

Error

Error messages (least verbose)

Implementations

impl LogLevel

pub fn should_log(&self, min_level: LogLevel) -> bool

Check if this level should be logged given a minimum level

Example

let min = LogLevel::Warn;
assert!(!LogLevel::Debug.should_log(min)); // Debug < Warn
assert!(!LogLevel::Info.should_log(min));  // Info < Warn
assert!(LogLevel::Warn.should_log(min));   // Warn >= Warn
assert!(LogLevel::Error.should_log(min));  // Error > Warn

Trait Implementations

impl Clone for LogLevel

fn clone(&self) -> LogLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LogLevel

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

Formats the value using the given formatter.

impl Default for LogLevel

fn default() -> LogLevel

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LogLevel

fn deserialize<__D>( __deserializer: __D, ) -> Result<LogLevel, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for LogLevel

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

Formats the value using the given formatter.

impl Hash for LogLevel

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 LogLevel

fn cmp(&self, other: &LogLevel) -> 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 LogLevel

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

fn partial_cmp(&self, other: &LogLevel) -> 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.

impl Serialize for LogLevel

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for LogLevel

impl Eq for LogLevel
