Enum CreateConstraintError 

pub enum CreateConstraintError {
    EquivalentConstraintExists(String),
    ConflictingConstraint(String),
    DuplicateName(String),
    DuplicateIndexName(String),
    BackingIndexConflict(String),
    UnsupportedPropertyType(String),
    DataViolation(String),
    Unsupported(&'static str),
}

Variants

EquivalentConstraintExists(String)

22N65 — an equivalent constraint already exists.

ConflictingConstraint(String)

22N66 — a conflicting constraint already exists on the same schema.

DuplicateName(String)

22N67 — a constraint with the same name (any kind) already exists.

DuplicateIndexName(String)

22N71 — name collides with an existing index name.

BackingIndexConflict(String)

22N73 — uniqueness/key constraint would conflict with an existing range index on the same schema.

UnsupportedPropertyType(String)

22N90 — property type unsupported in constraint.

DataViolation(String)

50N11 — existing data already violates the proposed constraint. Wraps the underlying crate::ConstraintViolation description.

Unsupported(&'static str)

Backend doesn’t support the catalog API.

Implementations

impl CreateConstraintError

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

Trait Implementations

impl Clone for CreateConstraintError

fn clone(&self) -> CreateConstraintError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CreateConstraintError

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

Formats the value using the given formatter.

impl Display for CreateConstraintError

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

Formats the value using the given formatter.

impl Error for CreateConstraintError

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.
