Enum Severity 

pub enum Severity {
    Critical,
    Error,
    Warning,
    Info,
    Debug,
}

Canopy’s severity vocabulary, narrowed from RFC 5424 to a five-level set with operator semantics:

• Debug: never participates in incidents (filed for the audit trail / per-server view only).
• Info, Warning: join an open incident for context but don’t open one or keep one open on their own.
• Error: opens an incident; sits in the per-group slack_open_delay holding window before the Slack notification ships.
• Critical: opens an incident and bypasses the holding window — the Slack notification is enqueued for immediate delivery.

Stored as text in Postgres; validated as this enum at the API layer. Default is Error (the most common severity for a deliberately filed event). The legacy syslog severities emergency / alert / notice have been retired — see the 2026-05-29-000000-0000_restrict_severities migration; the FromStr impl still accepts them as aliases for forward-compat with any device that hasn’t been updated.

Trait Implementations

impl Clone for Severity

fn clone(&self) -> Severity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Severity

impl Debug for Severity

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Severity

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Severity

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

Formats the value using the given formatter.

impl Eq for Severity

impl FromStr for Severity

type Err = ConversionError

The associated error which can be returned from parsing.

fn from_str(value: &str) -> Result<Self, ConversionError>

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

impl Hash for Severity

fn hash<__H: Hasher>(&self, state: &mut __H)

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 Severity

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

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

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for Severity

impl TryFrom<&String> for Severity

type Error = ConversionError

The type returned in the event of a conversion error.

fn try_from(value: &String) -> Result<Self, ConversionError>

Performs the conversion.

impl TryFrom<&str> for Severity

type Error = ConversionError

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self, ConversionError>

Performs the conversion.

impl TryFrom<String> for Severity

type Error = ConversionError

The type returned in the event of a conversion error.

fn try_from(value: String) -> Result<Self, ConversionError>

Performs the conversion.
