Enum Level 

pub enum Level {
    Info,
    Warning,
    Error,
    Fatal,
    Shutdown,
}

The severity level of a log entry.

Levels are assigned by each error type through the Loggable trait, which allows individual domain errors to decide their own severity without requiring a centralized match statement in the middleware.

The admin CLI (kosh-cli) uses these levels to apply color coding and filtering when rendering the log feed.

Variants

Info

Routine informational events: successful logins, uploads, health checks.

Warning

Events that are abnormal but non-fatal: client authentication failures, request conflicts, or resource not found responses.

Error

Unexpected failures that affect a single request but do not crash the service: database query errors, storage write failures.

Fatal

Critical failures that indicate the server may be in an unrecoverable state: vault directory missing, logger task crash.

Shutdown

A special sentinel level used to stop the logging service gracefully.

When the service receives an entry with this level, it stops its receive loop and allows the LoggerHandler to join cleanly. This is the “poison pill” pattern used instead of relying on channel closure, because the sender lives inside a OnceLock and is never dropped during normal operation.

Trait Implementations

impl<'__de, __Context> BorrowDecode<'__de, __Context> for Level

fn borrow_decode<__D: BorrowDecoder<'__de, Context = __Context>>( decoder: &mut __D, ) -> Result<Self, DecodeError>

Attempt to decode this type with the given [BorrowDecode].

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 Copy for Level

impl Debug for Level

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

Formats the value using the given formatter.

impl<__Context> Decode<__Context> for Level

fn decode<__D: Decoder<Context = __Context>>( decoder: &mut __D, ) -> Result<Self, DecodeError>

Attempt to decode this type with the given [Decode].

impl Encode for Level

fn encode<__E: Encoder>(&self, encoder: &mut __E) -> Result<(), EncodeError>

Encode a given type.

impl Eq for Level

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.
