Enum mz_transform::TransformError

pub enum TransformError {
    Internal(String),
    LetRecUnsupported,
    IdentifierMissing(LocalId),
}

Errors that can occur during a transformation.

Variants

Internal(String)

An unstructured error.

LetRecUnsupported

An ideally temporary error indicating transforms that do not support the MirRelationExpr::LetRec variant.

IdentifierMissing(LocalId)

A reference to an apparently unbound identifier.

Trait Implementations

impl Clone for TransformError

fn clone(&self) -> TransformError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TransformError

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

Formats the value using the given formatter.

impl Display for TransformError

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

Formats the value using the given formatter.

impl Error for TransformError

fn source(&self) -> Option<&(dyn Error + 'static)>

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, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl From<RecursionLimitError> for TransformError

fn from(error: RecursionLimitError) -> Self

Converts to this type from the input type.
