Enum rubble_templates_core::evaluator::EvaluationError [−][src]
pub enum EvaluationError { UnexpectedElements { last_expected: Option<SyntaxNode>, unexpected_elements: Vec<SyntaxNode>, }, UnknownSymbol { symbol: String, }, InvalidArguments { description: Option<String>, arguments: Vec<SyntaxNode>, }, InvalidValues { description: Option<String>, values: Vec<String>, }, }
Expand description
An error that can happen during evaluation.
Used by an Evaluator or Function to indicate that something bad happened. This is a very short description of what is happening - it can be created in a much narrow context, and then wrapped by an SyntaxError in a context where more info can be supplied.
It is intended to be used in cases when you don’t want to pass all unused data just in case to be able to create an SyntaxError if it happens. It contains only the most necessary info about the error.
