Variants

DuplicateTable(TableName)

A table name repeats.

DuplicateView(ViewName)

A view name repeats.

DuplicateColumn

A column repeats in one table.

Fields

table: TableName

Containing table.

column: ColumnName

Repeated column.

DuplicateConstraint

A constraint repeats in one table.

Fields

table: TableName

Containing table.

constraint: ConstraintName

Repeated constraint.

DuplicateIndex

An index repeats in one table.

Fields

table: TableName

Containing table.

index: IndexName

Repeated index.

DanglingDomain(DomainId)

A domain id is absent from the catalog.

DanglingColumn

A column reference is absent or crosses constraint scope.

Fields

table: TableName

Referencing table.

column: ColumnName

Missing column.

DanglingTable(TableName)

A table reference is absent.

DanglingView(ViewName)

A view reference is absent.

EmptyKey(ConstraintName)

A key has no columns.

NullablePrimaryKey(ColumnName)

Primary-key columns cannot be nullable.

DefaultAndGenerated(ColumnName)

A column declares both default and generation.

GeneratedCycle(ColumnName)

A generated column directly depends on itself.

InvalidDefault(ColumnName)

A default is rejected by its domain Shape.

InvalidGenerated(ColumnName)

A generated expression is rejected by its domain Shape.

ForeignKeyArity(ConstraintName)

Foreign key sides have different arity.

ForeignKeyDomain

Foreign key domains differ at an offset.

Fields

constraint: ConstraintName

Foreign-key constraint.

index: usize

Trait Implementations

impl Clone for SchemaError

fn clone(&self) -> SchemaError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SchemaError

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

Formats the value using the given formatter.

impl Display for SchemaError

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

Formats the value using the given formatter.

impl Eq for SchemaError

impl Error for SchemaError

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 SchemaError

fn eq(&self, other: &SchemaError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
