Enum TransitionError 

#[non_exhaustive]
pub enum TransitionError {
    EmptySymbolStack,
    IncorrectPoppedSymbol,
    UnknownNode,
}

Why a node cannot be applied to a StackState.

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.

EmptySymbolStack

A pop found no symbol to consume.

IncorrectPoppedSymbol

A pop found a different symbol on top.

UnknownNode

The node is not in the graph.
