Implementations

impl BytecodeVm

pub fn eval( bytecode: &Bytecode, ctx: &EvaluationContext, ) -> Result<bool, EngineError>

Evaluate a compiled CRUE bytecode condition to a boolean decision gate.

pub fn decode(bytecode: &Bytecode) -> Result<Vec<Instruction>, EngineError>

Decode raw CRUE bytecode into an explicit instruction sequence.

pub fn eval_program( program: &[Instruction], bytecode: &Bytecode, ctx: &EvaluationContext, ) -> Result<VmExit, EngineError>

Evaluate a decoded VM program against bytecode metadata/context.

pub fn eval_decision( bytecode: &Bytecode, ctx: &EvaluationContext, on_true: Decision, on_false: Decision, ) -> Result<Decision, EngineError>

Evaluate a compiled rule condition and emit a typed decision via VM instructions.

pub fn build_match_program( bytecode: &Bytecode, on_match: Decision, ) -> Result<Vec<Instruction>, EngineError>

Build a decoded VM program that emits on_match when the bytecode condition matches, and returns false (boolean) when it does not match.

pub fn eval_match_program( program: &[Instruction], bytecode: &Bytecode, ctx: &EvaluationContext, ) -> Result<Option<Decision>, EngineError>

Evaluate a prebuilt match program and return:

• Some(decision) when rule matched and emitted a decision
• None when rule condition evaluated to false
