Errors for all Structs and Functions in this Crate.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

EmptyForeignTableName

Error used when a ForeignKey has an empty foreign_table Name

EmptyForeignColumnName

Error used when a ForeignKey has an empty foreign_column Name

EmptyColumnName

Error used when a Column has an empty name

PrimaryKeyAndForeignKey

Error used when a Column has a PrimaryKey and ForeignKey at the same time

PrimaryKeyAndUnique

Error used when a Column has a PrimaryKey and Unique at the same time (Primary Key implies Unique, see here)

EmptyGeneratorExpr

Error used when a Generated Column has an empty Expression

EmptyViewSelect

Error used when a View has an empty select

EmptyTableName

Error used when a Table has an empty name

EmptyViewName

Error used when a View has an empty name

NoColumns

Error used when a Table has no Columns

MultiplePrimaryKeys

Error used when a Table has multiple Columns with a PrimaryKey

WithoutRowidNoPrimaryKey

Error used when a table marked as without_rowid has no Column with a PrimaryKey (WITHOUT ROWID tables need a Primary Key, see here)

EmptySchema

Error used when a Schema has no Tables or Views

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

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