Why a projection became stale.

Variants

TimeThreshold

Staleness threshold exceeded (time-based).

ExplicitInvalidation

Explicitly invalidated via API.

Fields

reason: String

SourceChanged

Source data changed upstream.

VersionMismatch

Schema or resolver version changed.

ImportLag

Upstream import pipeline is lagging behind source.

Fields

last_import_at: Option<String>

ISO 8601 timestamp of the last successful import, if any.

ImportFailure

The last import attempt failed.

Fields

error: String

Error from the failed import.

Trait Implementations

impl Clone for StaleCause

fn clone(&self) -> StaleCause

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StaleCause

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StaleCause

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for StaleCause

impl PartialEq for StaleCause

fn eq(&self, other: &StaleCause) -> 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 Serialize for StaleCause

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
