Enum Level 

pub enum Level {
    Info,
    Warn,
    Error,
    SelfError,
}

The level / severity of the Message. This can be thought of as the log level. This is used in conjunction to Component to indicate how a message should be routed.

Variants

Info

Indicates an informational message when everything is working properly.

Examples

• A job has completed successfully, e.g a backup
• A daily status update to confirm that everything is running correctly.

Warn

Used when something unexpected occurs that could be the source of an error, but requires the user to check whether it is actually an issue.

Examples

• A job took longer than normal
• A job failed that fails fairly regularly, but will presumably sort itself out soon.

Error

Indicates a failure has occurred.

Examples

• A program crashed / had a non-zero exit code
• A monitoring program detected that another program has not completed its job
  • Possibly indicating the program is not running
  • Or the program is malfunctioning
• A program restarted in attempt to recover itself, but is expected to recover safely

SelfError

Indicates a failure in the notifications own configuration / workings.

Examples

• Sent by MessageRouter to Root level MessageDestinations when a message cannot be sent to one or more destinations (e.g. network failure, invalid tokens)

Implementations

impl Level

pub fn min() -> Level

Gets the least severe Level

pub fn max() -> Level

Gets the most severe Level

Trait Implementations

impl Clone for Level

fn clone(&self) -> Level

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Level

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

Formats the value using the given formatter.

impl Default for Level

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Level

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Ord for Level

fn cmp(&self, other: &Self) -> 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 Level

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

fn partial_cmp(&self, other: &Self) -> 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 Level

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ValueEnum for Level

fn value_variants<'a>() -> &'a [Self]

All possible argument values, in display order.

fn to_possible_value<'a>(&self) -> Option<PossibleValue<'a>>

The canonical argument value.

fn from_str(input: &str, ignore_case: bool) -> Result<Self, String>

Parse an argument into Self.

impl Eq for Level

impl StructuralPartialEq for Level
