Enum ErrorKind 

pub enum ErrorKind {
    KeyConstruction,
    ConfigResolution,
    CacheRead,
    CacheReadTimeout,
    CacheWrite,
    TrackedTtlClamped,
    SerializationLoad,

}

Stable failure sites.

Variants

KeyConstruction

The key selector failed or panicked, or the identity could not form a key.

ConfigResolution

The policy provider or resolution failed for the invocation, a layer leaf was invalid, or a recovery or shadow option was rejected.

CacheRead

A process-local read failed, or a remote read failed for a reason other than its deadline.

CacheReadTimeout

A remote read did not answer within its read budget.

CacheWrite

A process-local or remote write failed, or the write stamp left the safe-integer domain.

TrackedTtlClamped

A tracked write asked for retention above the one-hour physical cap and was clamped: a configuration signal, not a failure.

SerializationLoad

The codec failed or panicked while decoding a stored payload.

SerializationDump

The codec failed or panicked while encoding a value for the remote layer.

Compression

zstd compression failed while preparing a remote write.

Invalidation

An explicit invalidation failed, including one made without a remote adapter.

Fallback

The source failed, panicked or exceeded its deadline; reported with in_fallback set.

Implementations

impl ErrorKind

pub fn as_str(self) -> &'static str

The snake_case label value shared with the TypeScript and Go ports and published by the bundled metric exporters.

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> ErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ErrorKind

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Display for ErrorKind

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

Formats the value using the given formatter.

impl Eq for ErrorKind

impl Hash for ErrorKind

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 PartialEq for ErrorKind

fn eq(&self, other: &ErrorKind) -> 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.
