Variants§

§

ConstEvalError(Box<str>, Box<ConstEvalError>)

§

LayoutError(LayoutError)

§

IncompleteExpr

§

IncompletePattern

§

TraitFunctionDefinition(TraitId, Name)

Trying to lower a trait function, instead of an implementation

ContinueWithoutLoop

§

BreakWithoutLoop

§

Loop

§

ImplementationError(String)

Something that should never happen and is definitely a bug, but we don’t want to panic if it happened
