Variants

KeyNotFound

Fields

key: String

DuplicateKey

Fields

key: String

Io(Error)

Corrupt

Fields

detail: String

RuleInvalid

Fields

detail: String

RuleOwned

Fields

detail: String

RuleNotFound

Fields

name: String

QueryError

Fields

detail: String

IngestError

Fields

detail: String

ReadOnly

Attempted mutation on a read-only as-of instance.

CommitOutOfRange

Requested commit index is beyond the valid range.

Fields

commit: u64

total: u64

ViewPropReadOnly

Attempted to write to a view-managed property.

Fields

view_name: String

CasConflict

A compare-and-set precondition was not satisfied.

expected is the commit seq the caller expected to see; actual is the commit seq recorded in the last-change map (or u64::MAX for NodeAbsent conflicts where the node unexpectedly exists).

Fields

key: String

expected: u64

actual: u64

MaskedReadOnly

Write statement submitted to a read-only masked query path.

Returned by [GraphDb::query_masked] when the Cypher input is a write statement (CREATE / MERGE / MATCH…SET / DELETE). The HTTP layer maps this to 400 Bad Request with body {"error":"masked queries are read-only"}.

Trait Implementations

impl Debug for GraphError

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

Formats the value using the given formatter.

impl Display for GraphError

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

Formats the value using the given formatter.

impl Error for GraphError

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<Error> for GraphError

fn from(e: Error) -> GraphError

Converts to this type from the input type.
