Expand description

Errors that can occur while handling a QGM model.

A bunch of the error types exist because our support for HIR ⇒ QGM conversion and QGM ⇒ MIR conversion is currently incomplete. They will be removed once these limitations are addressed.

Variants

UnsupportedHirRelationExpr(UnsupportedHirRelationExpr)

Indicates HIR ⇒ QGM conversion failure due to unsupported HirRelationExpr.

UnsupportedHirScalarExpr(UnsupportedHirScalarExpr)

Indicates HIR ⇒ QGM conversion failure due to unsupported HirScalarExpr.

UnsupportedBoxType(UnsupportedBoxType)

Indicates QGM ⇒ MIR conversion failure due to unsupported box type.

UnsupportedBoxScalarExpr(UnsupportedBoxScalarExpr)

Indicates QGM ⇒ MIR conversion failure due to unsupported scalar expression.

UnsupportedQuantifierType(UnsupportedQuantifierType)

Indicates QGM ⇒ MIR conversion failure due to unsupported quantifier type.

UnsupportedDecorrelation(UnsupportedDecorrelation)

Indicates QGM ⇒ MIR conversion failure due to lack of support for decorrelation.

Internal(Internal)

An unstructured error.
