Enum DiagnosticLevel 

pub enum DiagnosticLevel {
    Custom(&'static str),
    Info,
    Warning,
    Error,
    Fatal,
}

A severity level for labels messages.

These are ordered in the following way:

use diagnostic::DiagnosticLevel;

assert!(DiagnosticLevel::Fatal > DiagnosticLevel::Error);
assert!(DiagnosticLevel::Error > DiagnosticLevel::Warning);
assert!(DiagnosticLevel::Warning > DiagnosticLevel::Info);
assert!(DiagnosticLevel::Info > DiagnosticLevel::Custom("panic"));

Variants

Custom(&'static str)

A custom diagnostic level

Info

A useful information.

Warning

A warning that problems may arise

Error

An error.

Fatal

An unexpected bug.

Trait Implementations

impl Clone for DiagnosticLevel

fn clone(&self) -> DiagnosticLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DiagnosticLevel

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

Formats the value using the given formatter.

impl Default for DiagnosticLevel

fn default() -> DiagnosticLevel

Returns the “default value” for a type.

impl Deserialize<'static> for DiagnosticLevel

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

where __D: Deserializer<'static>,

Deserialize this value from the given Serde deserializer.

impl Hash for DiagnosticLevel

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 DiagnosticLevel

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

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

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

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.
