Structured domain failures.

Variants

Invalid

Invalid record value or derived identity.

Fields

field: &'static str

Safe field name.

message: &'static str

Safe failure summary.

Limit

Participant row limit exceeded.

Fields

participant: &'static str

Safe participant name.

observed: usize

Observed rows.

limit: usize

Maximum rows.

Duplicate(&'static str)

Duplicate identity in one staged participant.

Dangling(&'static str)

Lineage references an event absent from the same participant.

Conflict(&'static str)

Idempotency identity was reused for different content.

Canonical(CanonicalError)

Shared canonicalization failure.

Arrow(ArrowError)

Arrow construction failure.

Implementations

impl ProvenanceError

pub const fn code(&self) -> &'static str

Stable public error code.

Trait Implementations

impl Debug for ProvenanceError

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

Formats the value using the given formatter.

impl Display for ProvenanceError

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

Formats the value using the given formatter.

impl Error for ProvenanceError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<ArrowError> for ProvenanceError

fn from(source: ArrowError) -> Self

Converts to this type from the input type.

impl From<CanonicalError> for ProvenanceError

fn from(source: CanonicalError) -> Self

Converts to this type from the input type.
