    SchemaNotEnabled,
    ConstraintAlreadyExists,
    LabelNotFound(String),
    PropertyKeyNotFound(String),
    EdgeTypeNotFound(String),
    IndexNotFound(IndexId),
}

Catalog-related errors.

Variants

SchemaNotEnabled

Schema constraints are not enabled.

ConstraintAlreadyExists

The constraint already exists.

LabelNotFound(String)

The label does not exist.

PropertyKeyNotFound(String)

The property key does not exist.

EdgeTypeNotFound(String)

The edge type does not exist.

IndexNotFound(IndexId)

The index does not exist.

Trait Implementations

impl Clone for CatalogError

fn clone(&self) -> CatalogError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CatalogError

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

Formats the value using the given formatter.

impl Display for CatalogError

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

Formats the value using the given formatter.

impl Error for CatalogError

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 PartialEq for CatalogError

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