Struct TypedEvaluator 

pub struct TypedEvaluator<'expr, 'ctx, 'dyn_ctx, N: DomNavigator> { /* private fields */ }

A typed evaluator that allows binding arbitrary XPathValue<N> values.

This is used within run_with callbacks to set variables that cannot be represented as simple EvalValue (like nodes or sequences).

Implementations

impl<'expr, 'ctx, 'dyn_ctx, N: DomNavigator> TypedEvaluator<'expr, 'ctx, 'dyn_ctx, N>

pub fn set_variable_by_name( &mut self, name: &str, value: XPathValue<N>, ) -> Result<(), XPathError>

Set a variable by name to an arbitrary XPath value.

This allows binding nodes, sequences, empty sequences, or any other XPathValue<N> to an external variable.

Errors

Returns XPST0008 if the variable was not declared at compile time.

pub fn set_variable(&mut self, slot: VarSlotId, value: XPathValue<N>)

Set a variable by slot ID directly.

Use this when you already know the slot ID (e.g., from ExternalVar::slot).

pub fn context(&mut self) -> &mut DynamicContext<'ctx, N>

Get a reference to the dynamic context for advanced manipulation.
