execute_rule()

std::optional< std::any > MayaFlux::Yantra::ComputationGrammar::execute_rule ( const std::string &  rule_name, const std::any &  input, const ExecutionContext &  context  ) const

inline

Execute a specific rule by name.

Parameters

rule_name	Name of the rule to execute
input	Input data for the rule's executor
context	Execution context containing parameters and metadata

Returns

Result of rule execution, or nullopt if rule not found or doesn't match

Finds the named rule and executes it if its matcher function returns true for the given input and context. This allows for explicit rule invocation when the specific rule to apply is known.

Note

The rule's matcher is still evaluated even when invoked by name, ensuring that rules maintain their matching contracts
