Enum Severity 

#[repr(u8)]
pub enum Severity {
    Emerg = 0,
    Alert = 1,
    Crit = 2,
    Err = 3,
    Warning = 4,
    Notice = 5,
    Info = 6,
    Debug = 7,
}

Indicates how urgent a log message is.

Ordered from most critical (Emerg) to least (Debug).

Variants

Emerg = 0

System is unusable; immediate human intervention required.

Alert = 1

A condition that must be corrected immediately to prevent further damage.

Crit = 2

A serious failure that may still allow the system to keep running.

Err = 3

An error that prevented an operation from completing.

Warning = 4

Something unexpected happened, but the system can continue.

Notice = 5

A normal but significant event worth tracking.

Info = 6

Routine operational information confirming expected behaviour.

Debug = 7

Detailed information useful only when diagnosing problems.

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 Debug for Severity

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

Formats the value using the given formatter.

impl Display for Severity

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

Formats the value using the given formatter.

impl TryFrom<i32> for Severity

Accepts libc::c_int to support bridging from C syslog APIs that represent severities as plain integers.

type Error = IntToEnumError<Severity>

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<u8> for Severity

Delegates to the i32 implementation to keep conversion logic in one place.

type Error = IntToEnumError<Severity>

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for Severity
